What is molar volume and where can I find the molar volume for the elements?

Answer 1

You will probably have to work each one out.

The mass of one mole is given by the Ar. Now look up the density of the element, and divide the mass of one mole by the density.

If you are talking about gases, though, the sitaution is different, in that one mole of any gas has the same volume - 24 litres at room temperature and pressure (or 22.4 at 0C)
