Calculating Liquid Composition?

We have a process at 25C and 5bar. The stream in question contains (in molar terms) 30%methanol, 20%DME and 50%water. I have worked out that the vapour pressure of the three compounds in this process:

DME: 6.332atm
Methanol : 0.228atm
Water: 0.052atm

I must now estimate (in mole fractions) the composition of the liquid phase. Is this Raoults Law?

Thanks =] xx
