Answer:

Equal to 0.253 mol.

Explanation:

Hello,

In this case, since hydrogen and water are in a 2:2 molar relationship, the number of moles of hydrogen necessary to produce 0.253 mol of water will be also 0.253 mol as shown on the following stoichiometric factor:

[tex]n_{H_2}=0.253mol H_2O*\frac{2molH_2}{2molH_2O} =0.253mol H_2[/tex]

Therefore, The number of moles of hydrogen that is needed to produce 0.253 mol of water is equal to 0.253 mol.

Best regards.
