mass, volume, and density

Question

In this word problem the mass of Aluminum is 34.7 so how much is the volume (cm^3) and density ( g/cm^3)?

Answer 1

Density is mass per unit volume, or D = m/V

You know the mass = 34.7 g (one has to assume it is grams since units are not given).

You know need to either know the density so you can solve for the volume, or you need to know the volume so you can solve for density.  As it stands, you cannot answer this question as there is insufficient information.
