Description: A mixture of liquids A and B exhibits ideal behavior. At 84^∘ C, the total vapor pressure of a solution containing 1.2 moles of A and 2.3 moles of B is 331 mmHg . Upon the addition of another mole of B to the solution, the vapor pressure increases to 347 mmHg . Calculate the vapor pressures of pure A and B at 84^∘ C.

step 1 All right, for this question, we got to set up a system of equations. And we have two scenarios.
