Question 1\

A

and

B

form an ideal solution, with

x_(A)=0.320

.\ The vapor pressure of pure

A

is

84.3mmHg

, and that of

B

is

41.2mmHg

.\ The vapor of the above mixture is collected and then condensed into a liquid in a separate container.\ What are the partial pressures of

A

and

B

vapors after equilibrium is established above this new liquid?\

P_(A)=27mmHg,P_(B)=28mmHg

\

P_(A)=28mmHg,P_(B)=21mmHg

\

P_(A)=41mmHg,P_(B)=21mmHg

\

P_(A)=35mmHg,P_(B)=46mmHg

\

P_(A)=46mmHg,P_(B)=35mmHg
