Question

What is the vapor pressure of the solvent
in an aqueous solution at 25◦C of 0.29 m (molality) urea(CO(NH2)2), a nonelectrolyte? The vapor pressure of water at 25◦C is 23.76 Torr.
Answer in units of Tor

I want to use the mole fraction and multiply it by VP and add the two VP, but I don't know what to do with the molality so that's its useful..
