Answer:
131 mg
Explanation:
Percent yield = 89%
Actual yield = 117 mg
Percent yield is given by
[tex]\text{Percent yield}=\dfrac{\text{Actual yield}}{\text{Theoretical yield}}\times 100\\\Rightarrow 89=\dfrac{117}{\text{Theoretical yield}}\times 100\\\Rightarrow \text{Theoretical yield}=\dfrac{117}{89}\times 100\\\Rightarrow \text{Theoretical yield}=131.46\approx 131\ \text{mg}[/tex]
The theoretical yield, for this reaction is 131 mg.
