The volume is 68.1 \ "L" at "STP".

Explanation:

Well, assuming that the hydrogen gas is contained at "STP", then the molar volume would be 22.7*3=68.1 \ "L".

Due to the new conditions of "STP", the new molar volume using the ideal gas equation (PV=nRT) comes out as 22.7 \ "L".

So, 3 moles of hydrogen gas at "STP" will have a molar volume of
