# Molar volume calculation trouble watch

1. A 60cm^3 sample of Co weighs 0.075g; calculate its molar volume.

Molar Volume = Density over Mass

And now Im stuck, because I thought the 60cm^3 was the density; but got myself so confused :s. Ive tried m/gfm; and got myself hopelessly lost

Density is mass over volume.

Molar volume, if it is density over mass, should just be 1/volume right?

I thought;

Density = 0.075/22.4L

So 3.348214286x10^-3

then 3.348214286x10^-3 (over mass; 0.075)

=0.04464

Which is totally wrong; answer given is 22.4L
