A chemistry student has a sample of an unknown compound containing carbon, hydrogen, and oxygen. The mass of the sample is 2.50 g. After combustion, the student finds that 1.80 g of carbon dioxide, 0.75 g of water, and 0.20 g of oxygen are produced. Using mass balance calculations, determine the empirical formula of the unknown compound.
