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.
