Boiling_Point Elevation/Freezing_Point Depression T=mK where, for freezing point depression: T=T(puresolvent)T(solution) and for boiling point elevation: T=T(solution)T(puresolvent)m=(#molessolute/Kgsolvent)Kb=boilingpointelevationconstant.Kf=freezingpointdepressionconstant. Kb and Kf depend only on the SOLVENT. Below are some common values. Use these values for the calculations that follow. The freezing point of ethanol, CH3CH2OH, is 117.30C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in ethanol is chlorophyll A student dissolves 14.51 grams of chlorophyll, C55H72MgN4O5 (893.5 g/mol ), in 199.8grams of ethanol. Use the table of boiling and freezing point constants to answer the questions below. The molality of the solution is m. The freezing point of the solution is C. The boiling point of chloroform CHCl3 is 61.70C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in chloroform is testosterone. How many grams of testosterone, C19H28O2 ( 288.4g/mol ), must be dissolved in 293.0grams of chloroform to raise the boiling point by 0.300 C ? Refer to the table for the necessary boiling or freezing point constant
