How many moles of oxygen (o2) are required to completely react with 27.4 mol of h2 equation: 2h2+> 2h20

Answer : The number of moles of oxygen gas required are 13.7 moles.

Explanation : Given,

Moles of = 27.4 moles

The given balance chemical reaction is:

From the balanced chemical reaction we conclude that,

As, 2 moles of react with 1 mole of

So, 27.4 moles of react with mole of

Therefore, the number of moles of oxygen gas required are 13.7 moles.
