The reaction $2H_2(g)+O_2(g)2H_{2}O(g)$ is used to produce electricity in a hydrogen fuel cell. Suppose a fuel cell contains $150g$ of $H_2(g)$ and $1500g$ of $O_2(g)($each measured to two significant figures$).$

How many grams of water can form?

Select one

$1\mathrm{.}3{10}^{2}g$ of $H_{2}O$

B$.1\mathrm{.}0{10}^{2}g$ of $H_{2}O$

c$.2\mathrm{.}0{10}^{2}g$ of $H_{2}O$

D$.1\mathrm{.}5{10}^{2}g$ of $H_{2}O$
