A mixture of Nitrogen (N₂) and Helium (He) gases is contained in a pipe at 1.0 atm pressure and at 298 K. At one point in the pipe, the partial pressure of N₂ is 60.80 kPa and at a point 0.22 m apart, the partial pressure of N₂ is 20.31 kPa. The diffusion coefficient of the mixture is 0.612×10^-4 m².s^-1. Considering Universal gas constant as 8314 m³ mol^-1 K^-1, the steady-state flux of N₂ is n×10^-6 kg mol.s^-1.m^-2. The value of n is ______ (Rounded off to 2 decimal places)
