Equilibrium concentration of dissolved nitrogen (in wt.%, rounded off to three decimal places) in pure liquid iron, exposed to atmospheric air at 1873 K, is _______.
Given: Sieverts' law constant as a function of temperature (T; in Kelvin) is log₁₀K[N] = [-518 / T - 1.063] where K[N] has the dimension of atm-(1/2). Assume [hN] = [wt.%N] where [hN] is the activity of nitrogen with respect to 1 wt.% Henrian standard state.
