Vapour pressure of pure A = 100 torr, moles = 2. Vapour pressure of pure B = 80 torr, moles = 3. Total vapour pressure of mixture isA. 440 torrB. 460 torrC. 180 torrD. 88 torr

Vapour pressure of pure A = 100 torr, moles = 2. Vapour pressure of pu

1.	Vapour pressure of pure A = 100 torr, moles = 2. Vapour pressure of pure B = 80 torr, moles = 3. Total vapour pressure of mixture isA. 440 torrB. 460 torrC. 180 torrD. 88 torr
Answer» Correct Answer - D `P_("total")=p_(A)^(@)x_(A)+p_(B)^(@)x_(B)` `P_("total")=P_(A)+P_(B)=100xx(2)/(5)+80xx(3)/(5)=88` torr.
