Consider steady-state diffusion in a binary A-B liquid at constant temperature and pressure. The mole-fraction of A at two different locations is 0.8 and 0.1. Let 𝑁A1 be the diffusive flux of A calculated assuming B to be non-diffusing, and 𝑁A2 be the diffusive flux of A calculated assuming equimolar counter-diffusion. The quantity × 100 is____________(rounded off to one decimal place).
