[Tutorial: Colligative Calculations]: This tutorial will guide you through calculating the boiling point elevation and freezing point depression for an ideal solution. Consider the boiling point and freezing point for a solution made from 13.1g of ethanol (MM 46.07g/mol ) in 100.0mL of water (density 1.00 g/mL) Step 3a. Calculate changes in phase change temperatures. The molality of the solution is 2.84m (mol ethanol/kg water). The equation for the depression of freezing point is: T=Km where K is the freezing point depression constant and is dependent on the solvent, m is the molality of solution, and T is the change in temperature. If the K for water is 1.86C/m, how much does the temperature for the freezing point decrease
