Discussion and Conclusion

In this lab, a submarine Adventure: Density Saves The Day,; I had made many of the calculation for the best result of the lab.

My calculations section contains: the volume of the unknown metals, where I figure out the volume of each metal so that I will be able to determine its density in order to find its identity; the density of unknown metals, where I figure out the density of each metal so that I will be able to determine its identity; percent error between known and unknown metal densities, where I figure out my error on the calculation for finding the identity of the unknown metals; mass of water, where calculate to find out the mass of water by subtracting the mass of graduated cylinder with water by the mass of the graduated cylinder itself in order to find the density of ocean water; the density of ocean water; where I figure out the density of the ocean water by divided its mass by its volume, this will help me to find the density of the submarine as well since it’s equal to each other; volume of balloon needed to match salt water density, where I figure out the volume of the balloon by using the volume formula for the sphere shape which is representing the shape of the balloon; final volume of the submarine, where I divided its mass by its density to get its final volume so that I can create the perfect submarine for the experiment; final density of the submarine, where I added up all of the mass of balloon, pellets, and rubber band and divided by the volume of sphere so that I get the final density of my submarine and test if my submarine flow appropriately.

The lab experiment on the identity of the unknown metals went well except that I have made a little bit of error on my calculation of the mass of water. I didn’t how to measure the mass of water with the graduated cylinder. I would improve my study by memorizing the procedure and make sure that I deeply understand the lab and its procedures before performing

    6.03 Calorimetry Lab

    Using the buret to read the volume of water is a source of random error because it is marked to the nearest 0.1mL. Therefore, our data could be above or below the actual volume of water in the buret because we took our reading to the nearest 0.01mL, which increases our uncertainty level. Along with taking our volume readings to the nearest 0.01mL, a random error also arose when we took the reading of the temperature of the water. The thermometer only read to the nearest tens places, therefore our readings went to only the tenths place which could have been measured inaccurately giving rise to more uncertainty and random error within the lab. We were able to limit our uncertainty level when taking the masses of the beaker with and without water, by using the analytical balances which read to the nearest ±0.0001g.…

    Tin Foil Ship

    We were given a piece of tin foil to make into our ship. We formed a rectangular flat-bottomed ship with short sides all around it from our piece of tin foil. Next, using the formula to find the volume of an object, we calculated the volume of the ship that we had created. Then, to get our prediction, we used a calculation that took the volume of our ship, multiplied the volume of our ship by the density of the water and divided that answer by the weight of a penny. After that, we placed our ship into a container of water, and keeping an accurate count, placed one penny at a time into our ship until it sank to the bottom of the container of water. After that, we subtracted the predicted number of pennies from the actual number of pennies to…

    Step 2: The materials remaining are milk jugs, aluminum soda cans, and soda bottles. The next step involves the large water tank and nets for skimming the materials out of the bottom of the tank. Next, I simply put the rest of the materials in the tank. The only material that should float should be the milk jugs because they are less dense than the water. The milk jugs are 0.9 grams per cubic centimeter, the water is 1 gram per cubic centimeter. The aluminum soda cans and soda bottles sink because they are more dense than water. The aluminum soda cans are 2.7 grams per cubic centimeter and the soda bottles are 1.4 grams per cubic centimeter. If an object is more than 1.00 grams per cubic centimeter it will sink. If an object is under 1.00 grams per cubic centimeter it will float. The workers then take out the milk jugs floating above the water with their skimmers.…

    How do your results compare to the work of another group? Write out the name of the other group and their numbers. The numbers were different because we used different objects of the same material, like we both used iron but mason got 48.27 grams for a beginning weight when we got 108.15 grams, because they were different shapes or something, But the calculations we put those measurements in were the same though, and we both got different answers, i got 32.54 g/ml and Mason got 12.54 g/ml…

    Lab One: Laboratory Techniques and Measurements

    The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different elements and salts it boiled up to 74 Celsius in five minutes of boiling. Our understanding that only pure water boils up to 100 Celsius. Also, the longer it boils the higher the increase temperature and evaporation occurs; this recorder under data 2. The third we were able to conduct Volume of how much drops and volume of water can hold thin-stemmed pipet, this recorded under data 3. Then we moved to data 4 for mass measurement, it was estimating 7 objects by holding to objects, and obtaining actual mass using a digital scale and recorded in grams. The last few objects, we got closer with estimated mass to actual mass do to more experiments. The data 5 able to get knowledge of density by using digital scale and common products salt and isopropyl alcohol; we gain from this experiment, that more saturated solution the higher it mass. After we used irregular objects metal bolt and magnet to find a density and used displacement method, it recorded under data 6; by using the formula density equal to the mass of its volume. The 7th data using Archimedes’ Method, noted that using irregular objects by dropping them in water we got greater volume results then displacement water, also the tie of a string gives more mass to object.

    Precision, Accuracy, and Density Measurements

    This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well, to determine the mass, volume and density of water by using various types of measuring glasswear, such as beakers, graduated cylinder, pipet, etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also, there will be a density calibration graph, used to determine an unknown value, prepared using NaCl solutions of known concentration prepared in lab to determine the concentration of an "unknown" NaCl solution. (General chemistry 1, Lab Manual, p.13) For results, the most accurate and precise glasswear will be determined between the different types of measuring glasswear used.…
