Depression in freezing point - Physical methods for Non-volatile substances
Mol. Mass = (1000 Kf * w) /W* ΔT
Where, Kf stands for Molal depression constant of the solvent,
w stands for Mass of the compound, W=Mass of the solvent
ΔT stands for Depression in freezing point of the solvent (determined experimentally)
