Raoult's Law, Single Condensable Species: $p_i=$

A stream of air at $100C$ and $5260mmHg$ contains $10\mathrm{.}0\%$ water by volume.

$1$ Calculate the dew point and degrees of superheat of the air.

$2$ Calculate the percentage of the vapor that condenses and the final composition of the gas phase if the air is cooled to $80C$ at constant pressure.

$3$ Calculate the percentage condensation and the final gas$-$phase composition if$,$ instead of being cooled, the air is compressed isothermally to $8500$

$mmHg.$
