Challenge Problems
Push your limits with advanced challenges
A non-volatile solute creates a depression in freezing point of 3 K. If the van’t Hoff factor is measured as 1.5, determine the molar mass of the solute given K_f for water is 1.86 K kg/mol.
💡 Hint: First calculate m, then rearrange to find molar mass.
Consider a solution where the van’t Hoff factor of a solute is 3. If the osmotic pressure is observed to be 2.5 atm at 298 K, calculate the molality of the solution.
💡 Hint: First isolate n/V, then use the relation to find molality.
