H2SO4 solution containing 200.1 g of H2SO4 in 0.3500 L OF solution has a density of 1.3294 g/ml.calculate
(A) Mass%H2SO4(m/m)
(B)mass%H2O(m/m)
(C)Molarity
(D)Molality

a. mass H2SO4 = 200.1g
mass soln = 1.3294 g/mL x 350.0 mL = ?grams.
mass% H2SO4 = (mass H2SO4/total mass)*100 = ?
b. mass H2O = mass soln  mass H2SO4.
mass% H2O = (mass H2O/mass soln)*100 = ?
Note: Also 100%%H2SO4 = %H2O.
c. M = mols H2SO4/L soln (mols H2SO4 = 200.1/molar mass H2SO4).
d. m = mols/kg solvent. mass solvent you can get from b.
