Answer:
Percent yield is 71,2%
Explanation:
Acetaminophen is produced by p-aminophenol thus:
p-aminophenol + acetic anhydride → acetaminophen
The moles of p-aminophenol are:
[tex]0,75g*\frac{1 mol}{109,14 g}[/tex] = 6,87x10⁻³ moles
As molar ratio between p-aminophenol and acetaminophen is 1:1; the moles of acetaminophen with a theoretical yield are 6,87x10⁻³ moles, thus, theoretical grams are:
6,87x10⁻³ moles×[tex]\frac{151,163g}{1mol}[/tex] = 1,04 grams
As percent yield is real yield/theoretical yield times 100:
[tex]\frac{0,74}{1,04} *100[/tex] = 71,2%
I hope it helps!
