Secondly, how do you calculate percent by mass? Calculate the **mass percent**. Divide the **mass** of the element by the total **mass** of the compound and multiply by 100. This will give you the **mass percent** of the element. Example 1: **mass percent** = (2.01588/18.01528) x 100 = 0.11189 x 100 = 11.18%. Thus, the **mass percent** of Hydrogen atoms in a water molecule is 11.18%.

How do I calculate molecular mass?

**Key Points** The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
