If the molecular mass of a substance is 7.304 • 10²³ g, find its molar mass.

1.213 g/mol

Explanation:

We are given that the molecular mass is 7.304 × 10²³ g.

From avogadro's number, we know that;

1 mole of a substance = 6.022 × 10²³ molecules

Thus;

Molar mass = molecular mass/avogadro's number = (7.304 × 10²³)/(6.022 × 10²³) = 1.213 g/mol
