8. Compounds A and B form an ideal solution. The vapor pressure of pure A is P= 72.2 mmHg and a solution with a mole fraction of A of XA= 0.60 has a total vapor pressure of PTot= 59.6 mmHg. What is the vapor pressure of pure B?
Expert Solution
Step 1
Total vapor pressure of the solution, PT = 59.6 mm Hg
Vapor pressure of pure A, P˚A =72.2 mm Hg
Vapor pressure of pure A, P˚B = unknown
Mol fraction of A, xA = 0.60
Mol fraction of B, xB = 1- xA
=1-0.60
= 0.40
