A chemist combined chloroform ( CHCl 3 ) (CHCl3) and acetone ( C 3 H 6 O ) (C3H6O) to create a solution where the mole fraction of chloroform, χ chloroform , χchloroform, is 0.187 0.187 . The densities of chloroform and acetone are 1.48 g/mL 1.48 g/mL and 0.791 g/mL , 0.791 g/mL, respectively. Calculate the molarity of the solution.
