He following balanced equation shows the formation of water. 2H2 + O2 mc020-1.jpg 2H2O How many moles of oxygen (O2) are require

mrs_skeptik [129]

Answer : The correct option is, 13.7 mole

Solution : Given,

Moles of $H_2$ = 27.4 moles

The given balanced chemical reaction is,

$2H_2+O_2\rightarrow 2H_2O$

From the balanced chemical reaction, we conclude that

As, 2 moles of $H_2$ react with 1 moles of $O_2$

So, 27.4 moles of $H_2$ react with $\frac{27.4}{2}=13.7$ moles of $O_2$

Therefore, the number of moles of oxygen $O_2$ required are, 13.7 moles
