1. To find the density of the old pennies (80’s and earlier), 1st measure mass on the balance to the nearest 100th – example 31.57 g. 2. Measure the volume of the copper pennies sliding them slowly into a graduated cylinder that has 73.5 ml of water. 3. Record final volume of the pennies in the H2O. Subtract the Vtotal -Vwater = Vpennies . Divide m by v; D=m/v 4. Repeat steps 1- 3 for the new pennies (82’ & later). 5. Repeat steps 1- 3 for the cork stopper. Use a pencil tip to keep the stopper under water. 6. Repeat steps 1 – 3 for the rubber stopper. 7. Mass the diet soda in its’ can, then subtract the mass of can to obtain the mass of the liquid inside. 8. Read the volume on the bottom of the diet soda and record. Divide m by v; D = m/v 9. Repeat step 7-8 for the regular soda. 10. To find density of the water, first mass the graduated cylinder and record the container’s mass. 11. Then fill the cylinder to 73.5 ml and mass again. mtotal -mcylinder = mwater 12. Divide the mass of the water by the volume of the water (73.5 ml);; Divide m by v; D = m/v
