Directions: Do what is asked. The final answer should be in a complete sentence and in the correct number of significant figures. 1. An enzyme that breaks bacterial cell walls is called lysozyme. If a solution containing 0.150 g of this enzyme in 210 mL of the solution has an osmotic pressure of 0.127 kPa at 25 °C. Calculate the molar mass of lysozyme. 2. Glycerin (?3?8?3) is a nonvolatile nonelectrolyte with a density of 1.26 g/mL at 25 °C. Calculate the vapor pressure at 25 °C of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 25 °C is 3.17 kPa, and its density is1.00 g/mL. 3. Automotive antifreeze contains ethylene glycol, ?2?6?2, a nonvolatile nonelectrolyte, in water. Calculate the boiling point and freezing point of 25.0% by mass solution of ethylene glycol in water.
