Frequently Asked Questions
An empirical formula represents the simplest whole-number ratio of atoms of each element in a compound. For example, hydrogen peroxide (H2O2) has an empirical formula of HO.
Enter the number of elements (2-5), then input each element symbol (e.g., C, H, O) and its mass in grams or percentage. Click 'Calculate Empirical Formula' to get the result.
If you enter all percentages, they should sum to approximately 100%. The calculator will warn you if the sum is off by more than 0.5%. You can also enter masses in grams instead.
