Question

what is the percent yield of a product if you produced 38.86 g of the product, with a theoretical yield of 198.7 g? solve to 4 significant figures.

Explanation:

Step1: Recall the percent - yield formula

Percent yield formula is \(\text{Percent Yield}=\frac{\text{Actual Yield}}{\text{Theoretical Yield}}\times100\%\)

Step2: Substitute the given values into the formula

Given actual yield \(= 38.86\space g\) and theoretical yield \(=198.7\space g\)
\(\text{Percent Yield}=\frac{38.86}{198.7}\times 100\%\)
First, calculate \(\frac{38.86}{198.7}\approx0.1956\)
Then, \(0.1956\times100\% = 19.56\%\)

Answer:

\(19.56\%\)
