Answer : The number of moles of [tex]O_2[/tex] required are 0.835 moles.
Explanation : Given,
Moles of [tex]H_2[/tex] = 1.67 moles
The given balanced chemical reaction is,
[tex]2H_2+O_2\rightarrow 2H_2O[/tex]
By the stoichiometry we can say that, 2 moles of hydrogen gas react with 1 mole of oxygen gas to give 2 moles of water as a product.
From the balanced reaction we conclude that,
As, 2 moles of [tex]H_2[/tex] react with 1 mole of [tex]O_2[/tex]
So, 1.67 moles of [tex]H_2[/tex] react with [tex]\frac{1.67}{2}=0.835[/tex] mole of [tex]O_2[/tex]
Therefore, the number of moles of [tex]O_2[/tex] required are 0.835 moles.
