Chapter 3, Problem 150E
A 2.52-g sample of a compound containing only carbon, hydrogen, nitrogen, oxygen, and sulfur is burned in excess oxygen to yield 4.23 g of CO2 and 1.01 g of H2O. Another sample of the same compound, of mass 4.14 g, yields 2.11 g of SO3. A third sample, of mass 5.66 g, yields 2.27 g of HNO3. Calculate the empirical formula of the compound.
