Question

A solution contains 5.00g of urea per 0.100kg of water (COCNH2)2 if the vapour pressure of pure water at 25°c is 23.7ton. What is the vapour pressure of the solution
mols urea = grams/molar mass = ?
mols H2O = 100 g/molar mass = ?
Total mols = nurea + nH2O
mole fraction H2O = XH2O
XH2O = nH2O/total mols
p<sub>solution</sub> = X<sub>H2O</sub>*P<sup>o</sup><sub>H2O</sub>
Am not convinced
