Percent Composition Calculator




How to Use the Calculator

Enter the total mass of the compound and the mass of the specific element within that compound that you are interested in. Click on “Calculate” to get the percent composition of the element in the compound.

How It Calculates the Results

The percent composition of an element in a compound is calculated by dividing the mass of the element by the total mass of the compound and then multiplying by 100 to get the percentage.

Limitations of the Calculator

This calculator assumes that the masses entered are in grams and that they represent a single compound. It will not be accurate if the inputs are in different units or if the entered masses correspond to a mixture of different substances. Also, ensure that the total mass is greater than the mass of the single element.
