8. Calculat e the total vapor pressure of a solution made by dissolving 25.0 g of glucose (CaH0%) in 215 g of water at 50 °C. MMcan2ox-1802 g/mol, MMipo-18.02 g/mol. Vapor Pressure of Ho@ 50°C-92,5 tom) (Answer: 91.4 torr) (similar Q.71 page 558) 398K 9. A 150.0 mL sample of an aqueous solution at 25°C contains 15.2 mg of an unknown nonelectrolyte compound. If the solution has an osmotic pressure of 8.44 torr, what is the molar mass of the unknown compound? A) 223 g/mo B294 g/mol C) 341 g/mol D)448 g/mol E) 195 g/mol Lysozyme is an enzyme used to cleave cell walls. lysozyme in 100.0 mL results in an osmotic pressure of 1.32 x 10 molar mass of lysozyme. A solution made by dissolving 0.0750 g of atm at 25 °C. Calculate the 10. (Answer: 1.39 x 10* g/mol.) (similar Q. 83)
