Determination of Molecular Weight from Freezing Point Depression . In this experiment, AT denotes the freezing point depression. All answers must be reported to the proper number of significant figures. K-3.90 °C-kg/mol for lauric acid The molecular formula for benzoic acid is CH,CO,H. (Molar Mass = 122.12 g/mol.) Except for direct measurements, the calculation(s) from which any reported number is derived must be shown. Credit will not be given for a mere number when a calculation was required to determine that number. In short, show your work.
