The boiling point of diethyl ether, CH3CH2OCH2CH3, is 34.500 °C at 1 atmosphere. Kb(diethyl ether) = 2.02 °C/m
In a laboratory experiment, students synthesized a new compound and found that when 13.85 grams of the compound were dissolved in 283.2 grams of diethyl ether, the solution began to boil at 34.843 °C. The compound was also found to be nonvolatile and a non-electrolyte.
What is the molecular weight they determined for this compound ?

delta T = Kb*molality
Substitute and solve for m
m = mols/kg solvent
Substitute and solve for mols.
mols = grams/molar mass. You know grams and mols, solve for molar mass.
