What is the Molar Mass of HF?
The molar mass of HF is around 20 grams per mole, or 20.006 grams per mole, to be specific.
Molar Mass of Molecules
A molecule is incredibly tiny, and so a different method is needed to measure the mass of a molecule than the mass of larger substances. This method is molar mass, which is measured in kg/mol, but usually expressed as g/mol.
