Background: This lab is all about finding the density of a candy bar, and determining whether or not the candy bar will float or end up sinking in a glass of water. In order to investigate the principles of mass, you have to find the volume and density for four different types of candy bars. My question is, which candy bar will have the least amount of density?
Hypothesis: If a Twix has cookie inside, then it will have the least amount of density.
Materials:
4 candy bars( Snickers, Twix, 3 Musketeers, Milky way)
Balance
Ruler
Procedures: First, you try to find the volume measure by using L x W x H. You then measure the width using a ruler. Finally, find the mass of the candy bar by weighing it on the scale and find its density by using D=M/V.

Results:

Analysis: Out of all the all the candy bars, Snickers were more denser because it has caramel inside it making the mass a little bigger, so when comparing it to the other bars the Snickers weighs 17.41 and 3 Musketeers weighs 6.32. Density is related to whether it sinks or floats because if it is light the candy will float but, if it has a high amount of density then it will sink. The way I would predict if it could float on water, would be trying to get an estimated weight by placing it on the of my hand. My prediction was wrong because I just looked at the size of the candy bar, guessing that just because it was small It would float. Sincerely it didn’t work for all

    In this experiment, the experimenters found the density of solid objects and then the concentrations of solutions based on their densities. It was determined that as density increases, concentration does as well. The density of a substance is something that stays constant, for solutions of material the density is expected to increase in direct translation to the concentration increasing. The theory surrounding this lab was to see in practice how density could be determined with displacement and then to determine whether the density does in fact increase directly with the concentration.…

    Gummy Bear Experiment

    After we took that gummy bear out of the water the size of it had changed dramatically the thickness was 25mm the width was 18mm the height was 41mm and the final volume was 18450 mm 3 and that final mass was 13.28grams. Overall we could tell that there was a lot of osmosis and diffusion happening to the gummy bear. If we were to make this experiment better I would suggest leaving the gummy bear in water till it was fully diffused. Another way we could make this experiment better would be to use more expensive gummy bears so that they would not fall apart so easily. Overall I liked the experiment and thought that we got good data it was also fun seeing how much diffusion accord with our own eyes not just the smell of it…

    Marshmallow Less Dense Essay

    I am thinking if I mix half a cup of sugar, and one third of a cup of corn syrup, then that amount of ingredients will make the marshmallow less dense, since it is less amounts of corn syrup and sugar. I believe these amounts will make a marshmallow less dense because according to my research, the density of corn syrup is 1.37g while the density of sugar is 1.59g, and those units of measurements seem minute.…

    Lab for Chemistry

    The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart, taking into account error analysis and finally classifying the substances. In order to calculate this density, we first found the mass of the container that was to be holding the substances. We then found the volume of the substance, and lastly determined the mass of the container and substance. We subtracted (Container + Substance) – Container to find the mass of simply the substance. In order to distinguish density, we took the final mass divided by the volume, and identified the substances based on Density Charts we found online. Originally we hypothesized that we would be able to identify these substances based on the densities we calculated, yet this proved to be harder than it seemed, however our hypothesis was correct. We now could concluded the densities and identification. The density of Unknown Liquid 1 was 1.26 which was found to be Colorless Glycerin (also density of 1.26) and Unknown Liquid 2 was 0.88 or Rubbing Alcohol (colorless). Unknown Solid 1 has a density of 7.20 or Iron, Solid 2 is 2.59 and Aluminum, Solid 3 is 5.47 and Tin, while Solid 4 has a density of 9.81and Nickel? We…

    Density of Sprite

    Density of Sprite

    In chemistry, accuracy and precision are very important. Accuracy is the degree of conformity of a literature value and precision is a degree to which further calculated values show similar result. In this lab, the volume of the solution (diet or regular) is measured using the Pipette, Burette, and Graduated Cylinder respectively. The mass of the solution is then measured to calculate the density of the soda. Density is mass of a substance per unit volume2. How heavy the substance is according to its size or volume. The volume of liquid is measured in mL and mass in grams. Since, the density of water is 1g/cm3 ; therefore Diet Sprite's density should be equal to or a little bit more then water. The hypothesis was that regular Sprite will have higher density because it has a higher sugar concentration present which increases the mass per volume ratio of the solution. In this experiment only regular Sprite was used. The results are then compared to another group which calculated the density of Diet Sprite.…
