Answer : The mole fraction of the non-volatile solute in the solution is 0.195
Explanation :
According to the relative lowering of vapor pressure, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component of the solution multiplied by the vapor pressure of that component in the pure state.
Formula used :
where,
= vapor pressure of the pure solvent (acetone) = 266 torr
= vapor pressure of the solution = 214 torr
= mole fraction of solute = ?
Now put all the given values in the above formula, we get:
Therefore, the mole fraction of the non-volatile solute in the solution is 0.195
