At a certain temperature, the vapor pressure of pure benzene (C6H6) is 0.930 atm. A solution was prepared by dissolving 14.0 g of a non-dissociating, nonvolatile solute in 78.17 g of benzene at that temperature. The vapor pressure of the solution was found to be 0.899 atm. Assuming the solution behaves ideally, determine the molar mass of the solute.
