Calculate the vapor pressure of a solution made by dissolving 89.3 g of urea (molar mass=60.06 g/mol) in 198.5 mL of water at 35 Celsius (the vapor pressure of pure water is at 35 degrees Celsius is given in Change table 5.3. Assume the density of the solution is 1.00g/mL). What is the magnitude of vapor-pressure lowering?
