Combustion of 13.5 g of sample of an hydrocarbon yields 24.41 g CO2 and 14.49 g H2O. The molar mass of the compound is 246 g/mol. What are the empirical and molecular formulas?

A5.000 g sample of niso4 h2o decomposed to give 2.755 g of anhydrous niso4. what is the formula of the hydrate? what is the full chemical name for the hydrate? what is the molar mass of the hydrate? niso4•_h2o what is the mass % of water in the hydrate?
