A compound contains 4.07% hydrogen, 24.27% carbon and 71.65% chlorine.

1.	A compound contains 4.07% hydrogen, 24.27% carbon and 71.65% chlorine. Its molar mass is 98.96 g. What are its empirical and molecular formulas?
Answer» SOLUTION : Empirical FORMULA is `CH_2Cl` Molar mass = 98.96 G (given), Empirical formula mass of`CH_2Cl=49.4"Molar mass"divEFmass =98.96div49.48=2` Molecular formula `=(EF)xxn=(CH_2Cl)xx2=C_2H_4Cl_2`
