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

#3color(red)cancelcolor(black)"mol"*(22.7 \ "L")/(color(red)cancelcolor(black)"mol")=68.1 \ "L"#.
