A and B are two gases that are mixed together; 2.50 mol A is mixed with 0.85 mol B. If the final pressure of the mixture is 1.75 atm, what are the partial pressures of A and B?

Let us find Xa and Xb
a = = 2.50/(2.50+0.85) = 2.50/3.35 = 0.746
Xb = mol b/total moles = 0.85/(2.50+0.85) = 0.85/3.35 = 0.254
P is given as 1.75 atm
Pa = Xa x P = 0.746 x 1.75 = 1.31atm
Pb = Xb x P = 0.254 x 1.75 = 0.442atm
