A solution is made by dissolving 41.3 g urea (CH4N20), a nonelectrolyte, in 275 g water. Calculate the vapor pressure of this solution at 25°C and 45°C. vapor pressure of water 25°C 23.8 torr 45°C 71.9 torr vapor pressure at 25°C = torr vapor pressure at 45°C = torr

A 500mL solution is prepared by dissolving 125g of HCl in water. If the density of the solution is 1.65g/cm3, what is the mole fraction? a. 0.023 b. 0.088 c. 0.081 d. 0.15 e. 0.23   When I tried this I got 0.0388, which obviously isn't correct.

What is the mole fraction of water in a solution that contains 70.2 g of urea and 23.1 g of water? Molar mass urea = 60.06 g/mol, water 18.02 g/mol. O a. 0.52 O b.0.32 OC. 0.48 O d. 0.36 e. 0.42
