Answer:
632 g
Explanation:
- 2CH₃OH + 3O₂ → 2CO₂ + 4H₂O
First we convert 579 g of CO₂ into moles, using its molar mass:
- 579 g CO₂ ÷ 44 g/mol = 13.16 mol CO₂
Then we convert CO₂ moles into O₂ moles, using the stoichiometric coefficients:
- 13.16 mol CO₂ * [tex]\frac{3molO_2}{2molCO_2}[/tex] = 19.74 mol O₂
Finally we convert O₂ moles into grams, using its molar mass:
- 19.74 mol O₂ * 32 g/mol = 632 g
