A solution is made by dissolving 46.5g of urea, (CH4N2O) a nonelectrolyte, in 316g of water. Calculate the vapour pressure of this solution at 40 oC. (ans in torr, note the vapour pressure of pure water at 40 oC is 55.3 torr.)

I have been struggling with this equation for over three hours and i keep getting it wrong.. Please help!!!
