BRAINCAKECombustion Analysis
Many organic compounds contain carbon and hydrogen and when burnt in air produce carbon dioxide and water.
By calculating how many moles of carbon dioxide and water are formed, the moles of carbon and moles of hydrogen in the compound can be used to determine the empirical formula.
The empirical formula is the simplest whole number ratio of moles of each element in a compound.
