MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The depression in freezing point is given by T_f = i K_f m. For urea, being a non-electrolyte, the van 't Hoff factor i = 1. Thus, T_f m. To exhibit the minimum freezing point depression, the solution must have the minimum molality. Among the given options, 0.06 m is the minimum concentration. Therefore, the 0.06 m urea solution exhibits the minimum freezing point depression. Answer: 0.06 m
