Question

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? (a) 287 g (b) 3.5 * 10-3 g/mL
(c) 286.72 g/mL (d) 3.48 * 10-3 g/mL (e) 2.9 * 102 g/mL
