Pls answer number 5 thank you
1. A solution contains 10.0 g pentane, C5H12, 10.0 g hexane, C,H14 and 10.0 g benzene, C6H6. What is the mole fraction of hexane? 2. What is the mole fraction of ethanol, CH;CH20H, in an aqueous solution that is 20.0% ethanol by mass? 3. Sucrose is a nonvolatile, nonionizing solute in water. Determine the vapor pressure lowering, at 27°C, of a solution of 75.0 grams of sucrose, C12H2011, dissolved in 180. g of water. The vapor pressure of pure water at 27°C is 26.7 torr. Assume the solution is ideal. What is the vapor pressure of a aqueous solution containing 10% (by weight) ethylene glycol (62 g/mol) at 25ºC. PH20 = 24.3 torr at 25°C. 4. If 4.27 grams of sucrose, C12H22011, are dissolved in 15.2 grams of water, what will be the boiling point of the resulting solution? Ko for water = 0.512ºC/m. 5. 6. The freezing point of a solution of 1.048 g of an unknown nonelectrolyte dissolved in 36.21 g of benzene is 1.39°C. Pure benzene freezes at 5.48°C and its K; value is 5.12°C/m. What is the molecular weight of the compound? A 1.0 g sample of a molecular compound having a molecular weight of 100,000 g/mol is dissolved in 100. g of water. Calculate the osmotic pressure of the solution in torr at a temperature of 27°C. (Assume the volume of the solution is 100. mL.) 7.
