Chemistry - Mole Concept Question with Solution | TestHub

For the given series of reactions:

$N{H}_3(g)+O_2(g)\to NO(g)+H_{2}O(l)$

$NO(g)+O_2(g)\to N{O}_2(g)$

To obtain the maximum mass of $N{O}_2$ from a fixed mass of a mixture of $N{H}_3$ and $O_2$ gases, the ratio of the mass of $N{H}_3$ to $O_2$ should be:
