The common laboratory solvent benzene is often used to purify substances dissolved in it. The vapor pressure of benzene, CH6, is 73.03 mm Hg at 25 °C. In a laboratory experiment, students synthesized a new compound and found that when 9.071 grams of the compound were dissolved in 185.9 grams of benzene, the vapor pressure of the solution was 72.02 mm Hg. The compound was also found to be nonvolatile and a non- electrolyte. What is the molecular weight of this compound? benzene C,H6 = 78.12 g/mol. MW g/mol %3D
