A) 68 Torr
B) 140 Torr
C) 48 Torr
D) 72 Torr
E) 54 Torr
Correct Answer: D
Solution :
Moles of X, \[{{n}_{X}}=\frac{3}{3+2}=\frac{3}{5}\] Moles of Y, \[{{n}_{Y}}=\frac{2}{3+2}=\frac{2}{5}\] \[{{P}_{T}}={{P}_{X}}{{n}_{X}}+{{P}_{Y}}{{n}_{Y}}\] \[=80\times \frac{3}{5}+60\times \frac{2}{5}\] \[=48+24=72\,\text{Torr}\]You need to login to perform this action.
