## Is the molar mass of hydrogen 1 or 2?

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.

How do you find the molecular mass of H2?

1. Answer: The total sum of the masses of the atoms or elements present in the molecule is termed as molecular mass.
2. Molecular mass of H2 = 2 u.
