Question

Table 2. Dimensions of 250g Hanging Mass

Base Edge (cm) (hexagonal mass)*	Base Diameter (cm) (cylindrical mass)*	Height (cm)
2.3	N/A	5.7

*Fill in the column that corresponds to the mass provided in your kit. You will have EITHER a hexagonal mass or a cylindrical mass, not both.

Table 3. 250 g Hanging Mass Buoyancy Data

Object	Weight in Air (N)	Weight in Water (N)	Buoyancy Force (N)	Volume Displaced (mL)
250 g Hanging Mass	2.5	2.1	0.4	22
Rubber Stopper	0.2	0	0.2	14

Post-Lab Questions

2. Use the value of the buoyant force to calculate an experimental value of the volume of the 250 g mass in kg/m³ (F_b = ρ_LV_D g). The density of water is approximately 1,000 kg/m³. Show your work.
3. Use the measured dimensions of the 250 g mass to calculate the volume of the mass based on its shape (either hexagonal or cylindrical). Show your work.
4. Determine the percent difference between the measured volume of the 250 g mass and the value calculated from the buoyant force measurement. Show your work.
5. Using the fact that 1 mL = 1 x 10^-6 m³, compare the volume of the displaced water to the calculated volume of the mass from Post-Lab Question 3 with a percent error calculation. Show your work.
