Question (2points) The presence of a nomvolatile solute causes the freezing point of a solution to be lower than that of the pure solvent. Because freezing point depression depends only on solute concentration and not on the identity of the solute, freezins point depression can be used to determine the molar mass of a solute. 1st attempt. Part 1 (1 point) Mise Periodic Table 9 See Hint The freezing point of a solution prepared by dissolving 137.3 mg of caffeine in 10.0g of camphor is lower than that of pure camphor ( K s. 39.7C/m by 2.81C. What is the molar mass of catfeine? 9/mol Part 2 (1 point) SeeHint Elemental analysis of caffeine yields the followine results: 48.45%C,5.15%,1,20.87N and the remainder O. What is the molecutar formula of catfeine? List the elements in the order itven by the elemental analysis
