Answer:
2.07 mol O₂
Explanation:
First we need to write down the species present in the chemical equation, using the information given by the exercise:
- H₂S + O₂ → SO₂ + H₂O
However this equation <em>is not balanced</em>, so now we<u> balance it</u>:
- 2H₂S + 3O₂ → 2SO₂ + 2H₂O
Now we can use the stoichiometric ratio to <u>calculate the moles of oxygen </u>from the moles of sulfide dioxide:
- 1.38 molSO₂ *
= 2.07 mol O₂
