What is the volume v of a sample of 2.30 mol of copper? the atomic mass of copper (cu) is 63.5 g/mol, and the density of copper is 8.92×103kg/m3.

1.636 x 10^-5 m^3

Explanation:

As we know that

1 mol of copper = 63.5 g of copper

2.3 mol of copper = 63.5 x 2.3 = 146.05 g of copper = 0.146 kg of copper

Density of copper = 8.92 x 10^3 kg/m^3

The relation between mass and volume is given by

mass = volume x density

Thus, the volume of copper is 1.636 x 10^-5 m^3.
