Well, #1.5*mol# of hydrogen ATOMS would have a mass of #1.5*g#.

Explanation:

Of course, hydrogen normally exists as the dihydrogen molecule, #H_2#, i.e. a binuclear species. In fact, ALL the elemental gases, SAVE the NOBLE GASES, are binuclear; cf. #H_2#, #N_2#, #O_2#, #F_2#, and #Cl_2#.

And thus #1.5*mol# of #"dihydrogen gas"# has a mass of #3.0*g#.
