The partial pressure of zinc (in torr, rounded off to two decimal places) in equilibrium with liquid lead containing 0.03 mole % zinc at 900 K is _______.
Given: Vapour pressure of pure zinc (pZn) at 900 K is 0.027 atm. Henry's law coefficient (γoZn) for zinc at infinite dilute solution in lead on Raoultian scale is 8.55. 1 torr = 1.316 × 10⁻³ atm.
