$1.(810$ point$)$ Ethanol $($CH$\_3$CH$\_2$OH$)$ is reacted to produce acetaldehyde $($CH$\_3$CHO$)$

$(810$ point$)$ Ethanol $(C{H}_{3}C{H}_{2}OH)$ is reacted to produce acetaldehyde $(C{H}_3$CHO$)$ in the presence of air. After separation of the product, the output gas leaves with the following composition: $C{O}_2(0\mathrm{.}7\%),O_2(2\mathrm{.}1\%),CO(2\mathrm{.}3\%),H_2(7\mathrm{.}1\%),C{H}_4(2\mathrm{.}6\%),$ and $N_2(85\mathrm{.}2\%).$

$100\mathrm{.}0$

$($b$)$ How many kilograms of acetaldehyde are produced per kilogram of ethanol fed into the process?in the presence of air. After separation of the product, the output gas leaves with the following composition: CO$\_2(0\mathrm{.}7$
