"Volume" >500*LVolume>500L. 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 22.422.4 LL.

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

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