A$.$ Oxygen and carben doxide hwe Hewry's law constans of $769$ atan$-1./$mol and $29\mathrm{.}4$ atm$-$L$/$mol$.$ respectrvely, in water. If a pas at a total pressure of $1\mathrm{.}0$ atm has $20\%0_3$ and $1\%C{O}_2,$ whar itre the mintar coacentrations of $O_2$ mod $C{O}_2$ in sanurated water? is water a good solvent ta serubb $C{O}_2$ from air?

B$.$ Consider a bibe thint has a large supply of essentially pure oxygen molecules on the left end and essmarially puse nitrogen molecules ou the right end. The tube has leagti $2\mathrm{.}0cm$ and diameter $0\mathrm{.}1cm.$ The direscion $($whach points let to right$)$ once a steaty concentration profile is eutablished in the nube? What is $1$ anm nad $T=273K,$ bor you will oced to adjuse this value to the sysem temperanue and preswure $($hee S$023$ CIIEN $3210$ Lecture $$20$ bo noles$).$
