how to calculate molar mass? Molar mass formula

2

The mass of 1 mole of an element is the atomic mass of that element expressed in grams. For example; 1 mole of iron contains 6.022137×1023 iron atoms molar mass 55.85 g/mol.

Therefore, we can find the mass of each of the atoms that make up a substance whose molar mass we know.

matom=molar mass/NA

Accordingly, if we try to find the mass of an iron atom (the molar mass of iron is 55.85 g/mol):

We find mFe=(55.85 g/mol)/ (6.022137×1023 atoms/mol)=9.28×1023 g/atom.
