Question

What the awnser pls help me

Answer 1

Answer:

theoretical yield 73g, actual yield 65g

explanation:

$\% \: yield = \frac{actual \: yield}{theoretical \: yield} \times 100$

1)

$\frac{45}{52} \times 100 = 86.5\%$

2)

$\frac{37}{39} \times 100 = 9.49\%$

3)

$\frac{65}{73} \times 100 = 89.0\%$

4)

$\frac{20}{23} \times 100 = 87.0\%$

as you can see the third one (89.0%) has the highest percent yield: theoretical yield 73g, actual yield 65g
