A sample of a substance (containing only C, H, and N) is burned in oxygen.
8.696 g of CO2, 2.225 g of H2O and 4.446 g of NO are the sole products of combustion.
What is the empirical formula of the compound?
How can I find the empirical formula if they do not give me the mass of the compound in order to find out how much oxygen is present?
