1) Calculate moles: S = 45g/32g/mol; O = 60g/16g/mol. Divide by the smallest number to find the ratio, which gives the empirical formula SO3.
2) Use the percent composition to find the empirical formula by dividing by respective atomic masses and then the smallest mole number. Since the molar mass equals the empirical formula mass, the molecular formula is the same, C2H3Cl3.None?
