The equilibrium vapor pressure of pure chloroform (CHCl3) is 240.0 mm Hg at 30.0 degrees celsius. If you dissolve 1.2 grams of an unknown compound

The equilibrium vapor pressure of pure chloroform (CHCl3) is 240.0 mm Hg at 30.0 degrees celsius. If you dissolve 1.2 grams of an unknown compound in 40 mL of chloroform and the vapor pressure of the solution drops to 237.0 mm Hg, what is the molar mass of the unknown compound? Assume the vant Hoff factor is 1. (The density of chloroform is 1.48 g/mL.)
