# Problem: You are asked to determine the mass of a piece of copper using its reported density, 8.96 g/mL, and a 150-mL graduated cylinder. First, you add 105 mL of water to the graduated cylinder; then you place the piece of copper in the cylinder and record a volume of 137 mL. What is the mass of the copper reported with the correct number of significant figures?

###### FREE Expert Solution

volume copper = final volume water - initial volume water
volume copper = 137 mL - 105 mL
volume copper = 32 mL
