Molar mass is often used in other equations and formulas in chemistry, and is useful when finding other unknown variables of substances. Finding the molar mass of a molecule is one of the first skills taught in introductory chemistry courses. Molar mass is a physical property and therefore describes a physical change of a substance rather than a chemical change. Density, boiling point, color, and volume are other examples of physical properties. This equation allows you to enter a substance (element or compound) in empirical notation and calculate the molar mass.  The default units for this calculation are grams per mole (g/mol).

Examples of empirical notation:  H2O,  NaCl,  C21H30O2
