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

Explanation:

Of course, hydrogen normally exists as the dihydrogen molecule, H2, i.e. a binuclear species. In fact, ALL the elemental gases, SAVE the NOBLE GASES, are binuclear; cf. H2, N2, O2, F2, and Cl2.

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