Calculate the percent yield of a reaction where a student collected 16.8 grams of product and was expecting to collect 49.7 gram
masya89 [10]

Answer:

\boxed{\text{33.8 \%}}

Explanation:

\text{\% yield} = \dfrac{\text{actual yield}}{\text {theoretical yield}} \times\text{100 \%}

Data:

        Actual yield = 16.8 g

Theoretical yield = 49.7 g

Calculation:

\text{\% yield} = \dfrac{\text{16.8 g}}{\text {49.7 g}} \times\text{100 \%} = \boxed{\textbf{33.8 \%}}
