Q. $2 H_{2} + O_{2} \to 2 H_{2} O$
$2 g H_{2}$ and $1 O_{2}$ react to form $H_{2} O$

3.0 g

1.125 g

4.5 g

2.50 g

$4 R 2 H_{2} + 32 g O_{2} \to 36 g 2 H_{2} O$
Here $O_{2}$ is the limiting reactant
$32 g$ of $O_{2}$ gives $36 g$ of water
$1 g$ of $O_{2}$ gives $\frac{36}{32} g$ of water
$= 1.125 g$ of water
