<u>Answer:</u>
0.800 moles of will be produced when 0.400 moles of react and are decomposed
<u>Explanation:</u>
The decomposition of (aq) ------> 2C2H5OH (aq) + 2CO2
¬moles of = 0.400 moles
Moles of produced will be calculated by the formula,
Moles of CO2 = 0.400 moles of
Substituting the values,
Moles of = = 0.400*2 = 0.800 moles
Therefore, 0.800 moles of will be produced when 0.400 moles of react and are decomposed

Answer:
Percent yield = 88%
Explanation:
Given data:
Mass of C₇H₆O₃ = 200.0 g
Actual yield of aspirin = 231 g
Percent yield = ?
Solution:
Chemical equation:
C₇H₆O₃ + C₄H₆O₃ → C₉H₈O₄ + C₂H₄O₂
Number of moles of aspirin:
Number of moles = mass/molar mass
Number of moles = 200.0 g/ 138.12 g/mol
Number of moles = 1.45 mol
Now we will compare the moles of aspirin with C₇H₆O₃.
C₇H₆O₃ : C₉H₈O₄
1 : 1
1.45 : 1.45
Theoretical yield of aspirin:
Mass = number of moles × molar mass
Mass = 1.45 g × 180.158 g/mol
Mass = 261.23 g
Percent yield:
Percent yield =( actual yield / theoretical yield )× 100
Percent yield = (231 g/ 261.23 g)× 100
Percent yield = 0.88 × 100
Percent yield = 88%
