The common laboratory solvent benzene is often used to purify substances dissolved in it. The vapor pressure of benzene , C6H6, is 73.03mmHg at 25C. In a laboratory experiment, students synthesized a new compound and found that when 13.85 grams of the compound were dissolved in 154.6 grams of benzene, the vapor pressure of the solution was 70.85mmHg. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this compojind? (Benzene=C0H6=78.12g/mol)Molecularweight=g/mol
