Solve number 5
SOLVE THE FOLLOWING 1.00 g of nonvolatile sulfanilamide, C6H8O2N2S, is dissolved in 10.0 g of acetone, C3H60.The vapor pressure of pure acetone at the same temperature is 400 torr. Calculate the vapor pressure of the solution. 1. Predict the vapor pressure of a solution created by mixing 30.0g of Na2SO4 with 175g H20 at 25 °C. The vapor pressure of the pure solvent at 25 °C is 23.76 torr. 2. 3. Determine the molality of a water solution if the boiling temperature is 104.42°C 4. Calculate the boiling point for a solution that contains 0.325 mol of Ca3 (PO4)2 dissolved into 240g of H20 If 4.18 g of a nonionic solute is dissolved in 36.30 g of benzene, C6H6 , the freezing point is 2.70 °C. Find the molar mass of this solute. The freezing point of benzene is 5.53 °C and the Kf is 5.12 °C /m. 5.
