Question

2H2(g)+O2(g)→2H2O(g)

How many moles of H2 are needed to react with 5.0 moles of O2?

Expert Solution

Step 1

Number of moles is equal to the ratio of mass to molar mass.

Number of moles= $\frac{Mass}{Molar mass}$

Balanced chemical reaction is the reaction in which number of species present in the reactant is equal to the number of species present in the product.

Step 2

To determine number of moles of hydrogen required.

Balanced chemical reaction

$2 H_{2} (g) + O_{2} (g) \to_{}^{} 2 H_{2} O (g)$

Given data

Number of moles of O₂=5.0 moles.

Molar ratio of H₂ and O₂ is 2:1.

Number of moles of H₂ required= $2 \times Number of moles of O_{2} .$

Number of moles of H₂ required= $2 \times 5.0 = 10.0 moles .$
