Question

A chemical factory is making soda ash (NA2CO3) from sodium bicarbonate. The production manager calculates they will make 80 tons of soda ash in the next 8 hour shift. At the end of the shift they weigh the produced soda ash at 74.3 tons. What was their percent yield?

Answer 1

Answer:

$\boxed{\text{ 93 \%}}$

Explanation:

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

Data:

$\begin{array}{rcr}\text{Actual yield} & = & \text{74.3 T}\\\text{Theoretical yield} & = & \text{80 T}\\\end{array}$

Calculation:

$\text{\% yield} = \dfrac{\text{74.3 T}}{\text {80 T}} \times\text{100 \%} = \textbf{93 \%}}\\\\\text{The percent yield was } \boxed{\textbf{93 \%}}$
