Vapor pressure calculation?

Lysozyme is an enzyme that cleaves bacterial cell walls. A sample of lysozyme extracted from chicken egg white has a molar m of 13,930g. A quantity of 0.100g of this enzyme is dissolved in 150g of water at 25�C. Calculate the vapour pressure of this solution. The vapour pressure of water at 25�C is 23.76 mm Hg. Kf(H2O) = 1.86�C/m Kb(H2O) = 0.52�C/m
