This lab report examines the freezing point depression of a liquid solution. The purpose is to determine the average molar mass of the liquid and solid by measuring how much the freezing point is lowered with increasing concentration. Safety goggles and closed shoes are required. The conclusions will report the average molar mass in grams per mole for both the liquid and solid, along with the range.
