This tool helps chemists and students calculate the empirical formula of a compound by using the percentage composition of each element. Input the necessary data to obtain the simplest ratio of elements within a compound.
Calculations are based on standard chemical formulas and data provided by the authoritative source at SciLearn Sydney University. All calculations strictly adhere to these standards.
The empirical formula is calculated using the ratio of the moles of each element in the compound.
For instance, if a compound is made up of 40% Carbon, 6.7% Hydrogen, and 53.3% Oxygen, the empirical formula can be calculated as follows...
An empirical formula represents the simplest whole-number ratio of elements in a compound.
The molecular formula shows the actual number of atoms of each element in a compound, while the empirical formula shows the simplest ratio.
