XH2SO4 = 0.2 so
XH2O = 0.8
Take 1 mol of the solution. That will contain 0.8 mols H2O. How many grams is that?
0.8 mol x 18 gH2O/mol = 14.4 g or 0.0144 kg.
molality = mols H2SO4/kg solvent
0.2/0.0144 = ?m
In the aqueous solution of H2SO4 its mole fraction is 0.2 then closest value of molality of
solution is
(1) 13.9 (2) 9.8
(3) 10.2 (4) 11.2
