What the awnser pls help me

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
