Answer: 672.2 grams
Explanation:
With 564.1 kJ of heat energy, moles of ethanol can be combusted.
So, we need to find the formula mass of ethanol.
- The atomic mass of carbon is 12 g/mol.
- The atomic mass of oxygen is 16 g/mol.
- The atomic mass of hydrogen is 1 g/mol.
- So, the formula mass of ethanol is
g/mol.
Therefore, the mass of ethanol is grams.
Considering the reaction stoichiometry, the mass of oxygen gas that is required to produce 32.1 grams of maleic acid anhydride is 47.17 grams.
The balanced reaction is:
2 C₆H₆(l) + 9 O₂(g)→ 2 C₄H₂O₃(s) + 4 CO₂(g) + 4 H₂O(g)
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- C₆H₆: 2 moles
- O₂: 9 moles
- C₄H₂O₃: 2 moles
- CO₂: 4 moles
- H₂O: 4 moles
The molar mass of each compound is:
- C₆H₆: 78 g/mole
- O₂: 32 g/mole
- C₄H₂O₃: 98 g/mole
- CO₂: 44 g/mole
- H₂O: 18 g/mole
By reaction stoichiometry, the following amounts of mass of each compound participate in the reaction:
- C₆H₆: 2 moles× 78 g/mole= 156 grams
- O₂: 9 moles× 32 g/mole= 288 grams
- C₄H₂O₃: 2 moles× 98 g/mole= 196 grams
- CO₂: 4 moles× 44 g/mole= 176 grams
- H₂O: 4 moles× 18 g/mole= 72 grams
Then you can apply the following rule of three: If by stoichiometries 196 grams of C₄H₂O₃ are produced by 288 grams of O₂, 32.1 grams of C₄H₂O₃ are produced from how much mass of O₂?
<u><em>mass of O₂= 47.17 grams</em></u>
Finally, the mass of oxygen gas that is required to produce 32.1 grams of maleic acid anhydride is 47.17 grams.
