Answer:
The number of moles of hydrogen that is needed to produce 0.253 mol of water is 0.253.
Explanation:
The balanced reaction is:
2 H₂ + O₂ → 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
- H₂: 2 moles
- O₂: 1 mole
- H₂O: 2 moles
Then you can apply the following rule of three: if by stoichiometry 2 moles of water are produced from 2 moles of hydrogen, 0.253 moles of water are produced from how many moles of hydrogen?
[tex]amount of moles of hydrogen=\frac{0.253 moles of water* 2moles of hydrogen}{2 moles of water}[/tex]
amount of moles of hydrogen= 0.253 moles
The number of moles of hydrogen that is needed to produce 0.253 mol of water is 0.253.
