Q)
Two solutions of non-volatile solutes A and B are prepared. The molar mass ratio, $\large\frac{M_A}{M}=\frac{1}{2}$ Both are prepared as 5% solutions by weight in water. Calculate the ratio of the freezing point depressions, $\large\frac{(\Delta T_f)_A}{(\Delta T_f)_B}$ of the solutions. If the two solutions are mixed to prepared two new solutions,$S_1$ and $S_2$,the mixing ratio being 2 : 3 and 3 : 2 by volume for $S_1$ and $S_2$ respectively what would be the ratio $\large\frac{(\Delta T_f)_{s_1}}{(\Delta T_f)_{s_2}}$ ?
