Question / (5 points) Dissolving 4.080 g of an unknown non-electrolyte in 46.140 g of water produces a solution with a freezing point of -0.78 °C. What is the molar mass of the unknown non-electrolyte in grams per mole? The molal freezing point constant for water is 1.86 °C/molal. Enter your answer to the correct number of significant figures. Do not include units. Your Answer: Answer
Question 8 (5 points) A student prepared a 0.280 molal solution of sodium chloride in water. The freezing point of the solution was found to be -0.87 °C. What is the experimental value of the van't Hoff factor for sodium chloride under these conditions? The molal freezing point constant (Kf) for water is 1.86 °C/molal. Enter your answer to the correct number of significant figures. Your Answer:
