Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement

Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today. The complete lack of vitamin C (ascorbic acid) characterized by dark purple spots on the skin and rotting gums‚ a disease called scurvy‚ took the lives of many sailors up until the mid 1800s when the prevention was discovered. Consequently‚ British sailors became referred to as ‘limeys’ because of their daily habit of eating

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring

Lab 1 “Laboratory Techniques and Measurements” A. Water boils at 100C at sea level. If the water in this experiment did not boil at 100 C‚ what could be the reason? * We’re not at sea level; the pressure could be lower or higher. B. While heating two different samples of water at sea level‚ one boils at 102C and one boils at 99.2C. Calculate the percent error for each sample from the theoretical 100C. (show your work) * 1st Sample: 1.96% error * 2nd Sample: 0.81% error
