An ideal solution contains 40 mole % of A and 60 mole % of B at 80 degrees C. The vapor pressure of pure A and B at this temp are 480 torr and 890 torr. Calculate the vapor pressure of the solution.

P_A = X_A*P^o_A.

P_B = X_B*P^o_B.

P_total = P_A + P_B

A = 40 mole percent = 0.40 = X_A
B = 60 mole percent = 0.60 = X_B
