Challenge Problems
Push your limits with advanced challenges
Determine the molar mass of a solute if a solution containing 1.5 kg of solution, which is 3% by mass of the solute, has a freezing point depression of 1°C. Assume Kf for the solvent is 1.86 K kg mol-1.
💡 Hint: Use the relationships among mass percentage, freezing point depression, and molarity.
A chemist dissolves 80 g of a non-volatile solute in 200 g of water. The freezing point of the solution is measured at -2.5 °C. Determine the Kf of water assuming complete solubility.
💡 Hint: Use relationships between freezing point depression and molality.
