How many moles are in a 7.10cm × 7.10cm × 7.10cm cube of copper?
So I know the volume of the cube is 7.1x7.1x7.1=357.911cm^3 but I don't know how to go from the volume to the number of moles. Can someone help please?

To determine the number of moles, you need to determine the mass of the copper. To determine the mass, you need to know the volume and density of copper.
According to the website below, the density of copper is 8.96 g/cc
http://en.wikipedia.org/wiki/Copper
Mass = Volume * Density = 357.911 * 8.96 = 3206.88256 grams
Mass of 1 mole of copper = 63.456 grams
Number of moles = 3206.88256 ÷ 63.456 = 50.4544141 moles
