exit ticket\nyou were supposed to make 20g of a product, but you only obtained 16g.\nwhat is your percentage…

Explanation:

Step1: Recall percentage - yield formula

The formula for percentage yield is $\text{Percentage Yield}=\frac{\text{Actual Yield}}{\text{Theoretical Yield}}\times100%$.

Step2: Identify actual and theoretical yields

The theoretical yield is the amount of product that should be made, which is $20$ g. The actual yield is the amount of product actually obtained, which is $16$ g.

Step3: Substitute values into the formula

$\text{Percentage Yield}=\frac{16}{20}\times100%$. First, $\frac{16}{20}=0.8$. Then, $0.8\times100% = 80%$.

Answer:

$80%$
