to determine the empirical formula of compounds using a combustion analysis simulation. Background: Combustion analysis is a powerful technique for determining the simplest (or empirical) formula of a compound. Remember that a simplest formula is the lowest whole number ratio of elements that can represent the composition of a compound.

the molar mass of the empirical formula (EF) is always a multiple of the MW. Use the MW to determine by what factor you need to multiply the empirical formula to find the molecular formula. Example. Determine the molecular formula for a compound that contains 22.5% Na, 30.4% P and 47.1% O and a molar mass of 306 g/mol
