The boiling point of diethyl ether, CH3CH20CH2CH3, is 34.500 °C at 1 atmosphere. K(diethyl ether) = 2.02 °C/m In a laboratory experiment, students synthesized a new compound and found that when 12.54 grams of the compound were dissolved in 201.0 grams of diethyl ether, the solution began to boil at 35.200 °C. The compound was also found to be nonvolatile and a non- electrolyte. What is the molecular weight they determined for this compound ? g/mol
