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

Answer 1

mols urea = grams/molar mass = ?
mols H2O = 100 g/molar mass = ?
Total mols = nurea + nH2O
mole fraction H2O = XH2O
XH2O = nH2O/total mols
p_solution = X_H2O*P^o_H2O

Answer 2

Am not convinced
