One way of purifying gaseous H2 is to pass it under high pressure through the holes of a metals crystal structure. Palladium, which adopts a cubic closest packed structure, absorbs more H2 than any other element and is one of the metals used for this purpose. How the metal and H2 interact is unclear, but it is estimated that the density of absorbed H2 approaches that of liquid hydrogen (70.8 g/L). What volume (in L) of gaseous H2 (at STP) can be packed into the spaces of 1 dm3 of palladium metal?
