Some crushed ice was placed in a 400 mL beaker. Some of the ice was allowed to melt before the temperature was taken and recorded to be 0°C as temperature of the ice. A 20 % urea solution is accurately prepared from dissolving 2 grams urea in 8 grams of distilled water. This urea solution is placed in a test tube then submerged in the beaker with crushed ice. The temperature of the urea solution was taken three times(3X) at intervals of 30 seconds and was recorded to be -2°C, -4°C and -8°C respectively. The temperature was taken until the freezing point was reached indicated when 3 consecutive temperature readings were identical to be -8°C. This was recorded to be the freezing _point of the solution.

A CHM 126 student performed the "Determination of Molar Mass by Freezing Point Depression" experiment. He started the experiment by measuring the mass and freezing point of the pure solvent with minimal error. Instead of quickly finishing the experiment, he took a lunch break. After returning from lunch, he noted that the solvent had absorbed some impurities from the atmosphere. He went ahead and performed the rest of the experiment anyway. Assuming a negligible (very minor) change in the mass of the solvent after absorbing impurities, which of the following choices contains only correct statements: because of the experimental error, the measured ATwill increase, the measured molality will increase, and the measured molar mass will contain no additional error because of the experimental error, the measured ATwill decrease, the measured molality will decrease, and the measured molar mass will decrease because of the experimental error, the measured ATwill decrease, the measured molality…

Boiling Point Elevation/Freezing Point DepressionT = m KWhere: T = T(solution) - T(pure solvent) * m = (# moles solute / Kg solvent) Kb = boiling point elevation constant. Kf = freezing point depression constant. Kb and Kf depend only on the SOLVENT. Below are some common values. Use these values for the calculations that follow.
