The boiling point of the solvent is __________ $${ }^{\circ} \mathrm{C}$$.
Answer
82
Explanation
At any temperature, the vapour pressure of the solution is lower than that of the pure solvent. Hence vapour pressure- temperature curve of solution lies below that of solvent.
The more volatile liquid evaporates fast as compared to the less volatile liquid at a low temperature because the volume increases with respect to temperature so it has a low boiling point.
