What is the volume of 45 grams of #H_2# gas at STP?

1 Answer

Apr 2, 2016

#"Volume" >500*L#. We use the molar volume of an Ideal gas at STP.

Explanation:

It is known that at STP, 1 mol of Ideal gas occupies a volume of #22.4# #L#.

We assume, reasonably. that dihydrogen gas behaves ideally at STP.

Thus #V# #=# #(45*cancelg)/(2*cancelg*cancel(mol^-1)) xx 22.4*L*cancel(mol^-1# #=# #??L#
