Experiment 4: Density of the Mass SetIn this experiment, you will be become familiar with the mass set.MaterialsMass Set10 N Spring ScaleVernier CaliperProcedure1. Use the Vernier caliper to find the height of the 100 g mass (from the mass set). Record the height in Table 4. 2. Determine the uncertainty of the height measurement and record it in Table 4. 3. Repeat Steps 1 - 2 to measure the diameter of the 100 g mass. 4. Calculate the radius by dividing the diameter by two. Record the radius in Table 4. 5. Determine the uncertainty and record it in Table 4. 6. Calibrate the spring scale if necessary and hook the 100 g mass on the hooked end of the scale. 7. Confirm that that mass is 100 grams. Record the mass in Table 4. 8. Determine the uncertainty and record it in Table 4. 9. Use the following equation to calculate the density of the 100 g mass. Record the density in Table 4.
