1. A 1.189 g sample contains only vitamin C (C6H8O6) andsucralose (C12H19Cl3O8). When the sample is dissolved in water to atotal volume of 39.0 mL, the osmotic pressure of the solution is3.57 atm at 297 K. What is the mass percent of vitamin C andsucralose in the sample?
vitamin C: %
sucralose: %
2. A chemist combined chloroform (CHCl3) and acetone (C3H6O) tocreate a solution where the mole fraction of chloroform,χchloroform,χchloroform, is 0.187 The densities of chloroform andacetone are 1.48 g/mL and 0.791 g/mL, respectively.
Calculate the molarity of the solution.
molarity: MM
Calculate the molality of the solution.
