9. A sample weighing 0.546 g was dissolved in 15.0 g of benzene. The Freezing Point depression is 0.240°C. The k for benzene is 5.12 °Ckg/mol. Calculate the molar mass of the sample. 10. A 1.00*10³ g of protein sample was dissolved in an enough water to make a 1.00 mL solution. The osmotic pressure of this solution is 1.12 torr at 25.0°C. Calculate the molar mass of the protein sample. Given 1 atm = 760 torr, R = 0.08206 Latm/Kmol.
