We have two sets of concentration terms:
(1) Molality, mole fraction, %w/w:
These deal with the moles or the mass of the solution and can be directly converted into each other as they do not involve the volume of the solution.
(2) Molarity, %w/v, Strength of the solution in g/ lit.
These deal with the moles or mass of the species and relate it to the volume of the solution. The terms in this set can be converted into each other.
However to convert the terms in the first and second set into each other, the density of the solution is required.
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K

A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
