The structure of a chemical compound is a cube. If the length of the edge of the cube is 500 pm, what will be the volume of the cube expressed in mL?

P.-S.

1. Express the length in cm:

500\ pm\cdot \frac{10^{-12}\ cm}{10^{-2}\ pm} = 5\cdot 10^{-8}\ cm


2. The volume of the cube is V = L^3:

V = (5\cdot 10^{-8})^3\ cm^3\cdot \frac{1\ mL}{1\ cm^3} = \bf 1,25\cdot 10^{-22}\ mL
