Question

A certain liquid has vapor pressures of 50 Torr. 1 mol of an involatile solute is dissolved in 1 mol of this liquid. What is the vapor pressure of the liquid above this solution?
n solute = 1
n liquid = 1
Xsolute = 1/2 = 0.5
Xliquid = 1/2 = 0.5

pliquid = Xliquid*P<sup>o</sup><sub>normal</sub>
