Calculating Molar Mass

Building your molecule from up to four elements from the Periodic Table, this Formula Solver shows you how to calculate molar mass using Avogadro’s Number.

A mole represents 6.022×10²³ atoms. An element's atomic mass is the mass of a single atom of that element. The molar mass, therefore, is calculated by multiplying the atomic mass by the number of moles of that element.

Molar mass for a molecule is similarly determined by summing the molar masses of each component element in the molecule.

In this tutorial, build your molecule using the periodic table and step through the calculations for determining the molar mass.
