- To find the molar mass:
- For an element, refer to the atomic mass on a periodic table with units of grams.
- For a compound, determine the molar masses of the atoms in their formulas by multiplying the atomic mass by the number of atoms and adding them together1.
- Alternatively, calculate the molar mass by measuring the mass and the number of moles in a sample of the substance and dividing both amounts2.
- Note that molecular masses are calculated from the atomic masses of each nuclide, while molar masses are calculated from the standard atomic weights of each element3.
