For the reaction

$H_2(g)+C{O}_2(g)H_{2}O(g)+CO(g)$

at $700C,K_c=0\mathrm{.}534.$ Calculate the number of moles of $H_2$ that are present at equilibrium if a mixture of $0\mathrm{.}570$ mole of $CO$ and $0\mathrm{.}570$ mole of $H_{2}O$ is heated to $700C$ in a $20\mathrm{.}0L$ container. Round your answer to $3$ significant digits.
