Answer:

We can use the Ideal Gas Law, #PV=nRT#. Rearranging, #n/V=P/(RT)=112.6/(0.082xx293)=4.7#.

This answer is in #mol L^-1#, and each mole of #H_2# is #2# #g#, so the final answer is #9.4# #gL^-1#.

Explanation:

Conversions:

#20^oC=293# #K#

#1655# psi = #112.6# atm

Constant:

0.082 #L atm K^-1 mol^-1#
