For the reaction: $N_2(g)+2O_2(g)2N{O}_2(g),K_C=8\mathrm{.}3{10}^{-10}$ at $25C.$ What is the concentration of $N_2$ gas at equilibrium when the concentration of $N{O}_2$ is four times the concentration of $O_2$ gas?

$1\mathrm{.}9{10}^{10}M$

$8\mathrm{.}3{10}^{10}M$

$5\mathrm{.}2{10}^{-11}M$

$4\mathrm{.}8{10}^{9}M$

$2\mathrm{.}1{10}^{-10}M$
