A pure copper cube has an edge length of 2.00cm. How many copper atoms does it contain? (volume of a cube = (edge length)^3; density of copper = 8.96g/cm^3 )

DrBob222,
Calculate the volume. Use density and volume to calculate mass, convert mass to moles. Then you know 1 mole Cu contains 6.022E23 atoms.
