277517 On dissolving a non- volatile solute in a solvent, the vapor pressure of the solvent is decreased by $10 \mathrm{~mm}$ of mercury. The mole fraction of the solute in this solution is 0.2 . If the vapour pressure of the solvent is decreased by $20 \mathrm{~mm}$ of mercury by dissolving more solute, what is the mole fraction of solvent in this solution now?
