# How do I find the molar mass of an element?

Mar 13, 2014

The molar mass of an element is the amu or atomic mass unit from the periodic table.

For Carbon this would be 12.01 g/mole. Keep in mind that this value is actually the average atomic mass of all the carbon isotopes, so this accounts for a sample of carbon containing both Carbon-12 and Carbon-14 atoms.

Now one mole of carbon would contain $6.02 x {10}^{23}$ atoms.
If you created a pile of these atoms on a balance it. Would measure 12.01 g of Carbon or 12.01 g/mol.

This would hold true for every element, one mole of atoms would have a mass equal to the average atomic mass from the periodic table.
