Enter the atomic symbols and percentage masses for each of the elements present and press "calculate" to work out the empirical formula. If the data does not fit to a simple formula, the program will attempt to generate possible empirical formulae and will indicate how well these fit the percentage composition using the variance.

History. Sir Isaac Newton computed the speed of sound in air as 979 feet per second (298 m/s), which is too low by about 15%. Newton’s analysis was good save for neglecting the (then unknown) effect of rapidly-fluctuating temperature in a sound wave (in modern terms, sound wave compression and expansion of air is an adiabatic process, not an isothermal process).

Write the empirical formula by attaching these whole-number mole ratios as subscripts to the chemical symbol of each element. Order the elements according to the general rules for naming ionic and molecular compounds. Here’s an example: What is the empirical formula of a substance that is 40.0% carbon, 6.7% hydrogen, and 53.3% oxygen by mass?
