A mixture containing 2.0 mol each of $H_2$ and $O_2$ is ignited so that water is formed. The amount of water formed is
Some Basic Concepts of Chemistry
Solution:
$2H_{2}+O_{2} \to 2H_{2}O$
Two moles of $H_{2}$ require one mole of $O_{2}$ to give two moles or $36\, g$ of water. Here $H_{2}$ is the limiting reactant
