express your answer as a percentage to three significant figures.
percent yield = %
submit request answer

Explanation:

Step1: Recall the formula for percent yield

Percent yield = $\frac{\text{actual yield}}{\text{theoretical yield}}\times100\%$

Step2: Substitute the given values into the formula

Given actual yield = $12.1\ g$ and theoretical yield = $27.3\ g$.
Percent yield = $\frac{12.1}{27.3}\times100\%$

Step3: Calculate the value

$\frac{12.1}{27.3}\times100\%=\frac{1210}{27.3}\% \approx 44.3\%$

Answer:

$44.3\%$
