Use the value of the buoyant force to calculate an experimental value of the volume of all of the objects in \( \mathrm{kg} / \mathrm{m}^{3}\left(F_{b}=\rho_{L} V_{D} g\right) \). Show your work. Click here to enter text. Use the measured dimensions of the \( 250 \mathrm{~g} \) mass to calculate the volume of the mass based on its shape. Show your work. Click here to enter text. 4. Determine the percent difference between the measured volume of the \( 250 \mathrm{~g} \) mass and the value calculated from the buoyant force measurement. Show your work. Click here to enter text. 5. Using the fact that \( 1 \mathrm{~mL}=1 \times 10^{-6} \mathrm{~m}^{3} \), compare the volume of the displaced water to the calculated volume of the mass from Post-Lab Question 3 with a percent difference calculation. Show your work. Click here to enter text. 6. Are the three experimental values of the volume of the \( 250 \mathrm{~g} \) mass (from Archimedes' Principle) larger or smaller than the calculated value using the caliper measurements? Why? Which of the three values for volume is more accurate? Which of the two experimental volumes are more accurate? Explain. Click here to enter text. 7. Use the experimental weight and volume of the rubber stopper to calculate the density of the stopper in \( \mathrm{kg} / \mathrm{m} 3 \) using the equation \( \rho=m / v \). Show your work. Click here to enter text. 8. Research the density of rubber stopper on the internet and compare your measured value of the density with the values listed online.
