Answer:

theoretical yield 73g, actual yield 65g

explanation:

[tex]\% \: yield = \frac{actual \: yield}{theoretical \: yield} \times 100[/tex]

1)

[tex] \frac{45}{52} \times 100 = 86.5\%[/tex]

2)

[tex] \frac{37}{39} \times 100 = 9.49\%[/tex]

3)

[tex] \frac{65}{73} \times 100 = 89.0\%[/tex]

4)

[tex] \frac{20}{23} \times 100 = 87.0\%[/tex]

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