	<onlyinclude>'''Molar mass''' (M) is a physical property, defined as the [[mass]] of a given [[element]] or [[molecule]] per [[mole]] of that substance.

By knowing the molar mass of a substance, having any mass of that substance allows one to know how many moles of it they have. This is given by the equation

<center><m>n=\frac{m}{M}</m></center>

where:

<m>m</m> is the mass of the substance in grams
<m>M</m> is the molar mass of the substance
<m>n</m> is the amount in moles of that substance
