A gas mixture with a total molar concentration of $70\mathrm{.}0$ mol$/$m$3$ contains $5\%$ CO$2,15\%$ H$2,45\%$ O$2,$ and $35\%$ H$2$O by volume. The absolute velocities of each species are $-5,-10,-2,$ and $15$ m$/$s$,$ respectively, all in the direction of the z$-$axis. Determine the molar diffusion flux, JCO$2$and JO$2.$
