Problem: An experiment is performed to determine if pennies are made of pure copper. The mass of 11 pennies was measured on a balance and found to be 26.951 g. The volume was found by dropping the 11 pennies into a graduated cylinder initially containing 10.00 mL of water. The volume after the pennies were added was 12.90 mL.Calculate the density of the pennies.

Density represents the mass of an object or compound within a given volume. When calculating density, we use the following equation:

$\overline{){\mathbf{density}}{\mathbf{=}}\frac{\mathbf{mass}}{\mathbf{volume}}}$
