The common laboratory solvent chloroform is often used to purify substances dissolved in it. The vapor pressure of chloroform, CHCl3, is 173.11 mm Hg at 25 degrees C. In a laboratory experiment, students synthesized a new compound and found that when 16.21 grams of the compound were dissolved in 281.6 grams of chloroform, the vapor pressure of the solution was 169.08 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this comound?
chloroform = CHCl3 = 119.40 g/mol
MW = ____ g/mol
