The boiling point of ethanol, CH3CH2OH, is 78.500 °C at 1 atmosphere. K(ethanol) = 1.22 °C/m In a laboratory experiment, students synthesized a new compound and found that when 11.56 grams of the compound were dissolved in 278.8 grams of ethanol, the solution began to boil at 78.776 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound ?
