If I understand your question, it would probably be how to calculate the mass of a molecule.

ex.

N2

mass N2 - 2(14.001) = 28.002 g/mol

Thus 1 molecule of N2 = 28.002 g/mol

You remember that 1 mol of a material contains 6.022 x 10^23 molecules. So convert what you have in grams to moles, and multiply by 6.022 x 10^23.
