A mixture of Nitrogen (N\(_2\)) 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 N\(_2\) is 60.80 kPa and at a point 0.22 m apart, the partial pressure of N\(_2\) is 20.31 kPa. The diffusion coefficient of the mixture is \(0.612 \times 10^{-4}\) m\(^2\).s\(^{-1}\). Considering Universal gas constant as 8314 m\(^3\).Pa.kg mol\(^{-1}\).K\(^{-1}\), the steady-state flux of N\(_2\) is \(n \times 10^{-6}\) kg mol.s\(^{-1}\).m\(^{-2}\). The value of \(n\) is _________ (Rounded off to 2 decimal places)
