What mass in grams of NaCl would need to be added to 5201 g of water to increase the boiling temperature of the solution by 1.500 "C7 (Kb for water is 0.5100 °C/m) 1 A 83.5 g sample of a nonelectrolyte is dissolved in 390.5 g of water. The solution is detemined to have a boiling point of 102.3 C. What is the molar mass of the compound? (Kb for water is 0.510 "C/m). What is the molarity of a solution of a polypeptide which has an osmotic pressure of 0.103 atm at 37.0 °C? The freezing point of pure benzene (CaH) is 5.49 °C. The freezing point of a solution made using toluene (C-Hi) in benzene is determined to be -13.0 °C. What is the molality of the toluene? (K benzene =5.12 "Cim) When 2.63 g of a polypeptide is dissolved in 687 ml of water, the resulting solution is found to have an osmotic pressure of 0.125 atm at 37.0 C What is the molar mass of the polypeptide? (Assume the volume doesn't change when the polypeptide is added) 2. 3. 4. 5n
