MDCAT Chemistry QUESTION #4380
Question 1
If $\%$ yield is $80\%$ and actual yield is $20\ g$, what will be the theoretical yield?
  • 20 g
  • 25 g✔️
  • 30 g
  • 40 g
Correct Answer Explanation
$\% yield = \dfrac{actual\ yield}{theoretical\ yield} \times 100$. Rearranging: $theoretical\ yield = \dfrac{actual\ yield}{\% yield} \times 100 = \dfrac{20}{80} \times 100 = 25\ g$.
