To calculate the theoretical yield, we will start with the mass of salicylic acid that you have reported 3 .0028 grams.
00:17
And then recognize from your balanced chemical reaction that one -mole salicylic acid yields one mole of aspirin.
00:26
First, we'll convert the salicylic acid into mole salicylic acid by dividing by its molar mass.
00:32
This you can look up or calculate on your own.
00:34
Once we have moles salicylic acid, and once we have one mole salicylic acid, knowing that one mole salicylic acid yields one mole aspirin, we also have moles aspirin.
00:50
Whatever this calculation is, that's the moles of aspirin that we should be able to create.
00:54
We'll then multiply that by the molar mass of aspirin to get grams aspirin that we should be able to create in theory.
01:02
That's why we call it the theoretical yield.
01:05
So at 100 % yield, you should be getting 3 .9167 grams of aspirin...
