One mole of hydrogen gas (H2) would have a mass of 2.01588 grams, and would occupy 22.4 liters at STP.

3.0 liters of H2 at STP would contain 3/22.4 moles of hydrogen, so:

(2.01588 * 3.0)/22.4 = 0.270 grams of hydrogen gas.

Grams are a dry conversion where as Liters are a liquid conversion I think so I am not sure

Good Luck
