The vspour preesure of two pure liquids A and B are 5 and 10 torr respectively. Calculte the total pressure of the solution (in torr) obtainrd by mixing 2 mole of A and 3 mole of B.

120 toor

36 toor

88 torr

180 toor

Text Solution

Verified by Experts

The correct Answer is:

`P_(m) = P_(A)^(@)X_(A) + P_(B)^(@). X_(B)`
`P_(m) = 100 xx 2/5 + 80 xx 3/5=40 + 48 = 88` torr
