An oxygen-permeable YBa₂Cu₃O_7−δ membrane 1 cm thick operates at 700 °C between pressurized air at 11 bar and pure O₂ at 1 bar. The steady-state O₂ gas production is 0.84 mL at atmospheric pressure and 20 °C (molar volume 24 L/mol) per square meter every second.

Calculate the O flux, O atom flux, and, finally, Do with Kyox = 4.3 bar (to obtain the O gradient across the membrane) and with molar YBaCu3O7-5 volume of 10-4 m/mol.
