In order to determine the molar mass of an unkown non-electrolyte through FP depression experiment, the following data was collected:
Mass of test tube = 123.2g, mass of test tube and cyclohexane = 132.11g, mass of test tube, cyclohexane and non-electrolyte = 134.11g,

FP of pure cyclohexane = 6.4C, FP of the non-electrolyte in cyclohexane = 2.9C

If Kfp for cyclohexane = -20C/m, calculate the molar mass of the non-electrolyte.

Please show how to do it (decent handwriting and organization is appreciated if written on paper)
