A compound X contains only the elements H, C, O, and S. A 5.00 g sample undergoes complete combustion to give 1.48 g of H2O(water) and 4.83 g of CO2(carbon dioxide), and a certain amount of SO2 that is further oxidized to SO3(sulfite) and dissolved in the water to produce the H2SO4 (sulfuric acid).On titration of H2SO4 (sulfuric acid), 109.8 mL of 1.00 M NaOH(sodium hydroxide) is required to completely react.
How can calculate the empirical formula of X when 5.00 g of X is titrated with NaOH, it is found that X has two acetic hydrogen and that 54.9 mL of 1.00 M NaOH is needed to completely neutralize it. Calculate the molecular formula of X?
