Use the following steps to determinr the percent error of the freezing point depressions you determined experimentally from the expected freezing point depression for each solute. Show sample calculations for sodium chloride solution. a. Use the actual molar mass of each solute to determine the expected motality of 0.234g of each solute in 4.00x10-3kg of water. Sample Calculation: b. Determine the expected freezing point depression for a solution with this motality. Sample Calculation: c. Determine the percent error of the freezing point depression you determine experimentally from the expected freezing point depression for each solute. Sample Calculation:
We can calculate the amount of freezing point depression that will occur using the following equation: ΔT = ikfm where ΔT is the amount of the change in the freezing point, i is the number of particles dissolved, kf is a constant (different for each solvent), and m is the concentration of dissolved material. This concentration has units of mol per kg solvent. With this in mind, let's calculate the amount of depression that will occur when 5 g of sugar (sucrose) is dissolved into 0.250 kg of water. Remember when sucrose dissolves in water remains as one particle. The kf for water is 0.512 0C/m. Report your answer with two decimal points and no units.
