A compound is composed of carbon, hydrogen, nitrogen and oxygen. When a 1.500-g sample of the compound is completely combusted, it yields 1.476 g of CO2and 0.605 g of H2O. In a separate analysis to determine nitrogen, 1.500 g of the compound is found to produce 0.313 g of N2. (a) Calculate the mass percent of each element in the compound. (b) Determine the empirical formula of the compound. (c) If the compound has a molar mass of 134 g/mol, what is the molecular formula?
A student heated a 3.32-g sample of a hydrate and recovered 2.02 g of an anhydrous compound.
