Unit #7CALCULATIONS BASED ON FORMULAE
7.7 - Percent Composition of Compounds

The proportion by mass of each element in a compound is called percent composition.

Here is how to determine the percent composition for a compound.
Take a look at a sample calculation.

To minimize errors due to rounding off numbers, keep as many significant figures in the calculations as possible.
