**How to calculate percentage composition? Yahoo Answers**

The percent composition is obtained by dividing the mass of each individual element in 1 mole of the compound by the total molar mass of the compound. That gives us the fractional composition. To get the percent composition we just need to follow up with a quick multiplication by 100. For all those math lovers, let's look at the definition expressed in equation form:... In order to find percentage composition you have to know the atomic weight of the atoms and find the molecular weight of the compound. Then you should use this formula,

**Calculating Percent Composition and Determining**
