Answer 1

See the explanations

Step-by-step explanation:

In the Baeyer-Villiger reaction, we will produce an ester from a ketone (see the first reaction). In our case, the ketone is Acetophenone therefore phenyl acetate would be produced.

Now, for the mass calculation, we have to keep in mind that we have a reaction with a 1:1 ratio. So, if we have 0.02 moles of acetophenone and 0.036 moles of m-CPBA the limiting reagent would be the smallest value in this case acetophenone.

Additionally, if we have a 1:1 ratio and the limiting reagent is 0.02 moles of acetophenone we will have as product 0.02 of phenyl acetate, if we take into account the molar mass of phenyl acetate (136.05 g/mol), we can do the final calculation:

`0.02~mol~acetophenone(1~mol~phenyl acetate)/(1~mol~acetophenone)(136.05~g~phenyl acetate)/(1~mol~phenyl acetate)=2.72~g~phenyl acetate`

I hope it helps!
