Vapor Pressure of a Urea Solution

A solution is prepared by dissolving 9.0 g of urea (a nonelectrolyte) in 360 g of water at 25.0°C. If the vapor pressure of pure water at 25.0°C is 23.80 mmHg, what is the vapor pressure of the urea solution at 25.0°C in mmHg?

The molar mass of urea is 60 g/mol and the molar mass of water is 18 g/mol.
