760 mmHg = 1.0 atm
590 mmHg = 590 x 1.0 / 760 = 0.776 atm
answer = 0.776 atm
2) 1.0 mmHg = 0.1333 kPa
590 mmHg = 590 x 0.1333 / 1.0 = 78.6 kPa
answer = 78.6 kPa

When heated at high temperatures, a diatomic vapor disassociates as follows: A2(g) = 2A(9) In one experiment, a chemist finds that when 0.0500 mole of A2 was placed in a flask of volume 0.528 L at 590 K, the degree of dissociation (that is, the fraction of A, dissociated) was 0.0296. Calculate K and Kp for the reaction at this temperature. Ke: Кр:
