The bitter-tasting compound quinine is a component of tonic water and is used as a protection against malaria. It contains only C, H, N and O. When a sample of mass 0.487 g was burned, 1.321 g of carbon dioxide, 0.325 g of water, and 0.0421 g of nitrogen were produced. The molar mass of quinine is 324 g/mol. Determine the empirical and molecular formulas of quinine. (Type your answer using the format CO2 for CO2 and use the order CHNO)
