Crystallization Report - What is a Good Yield?

[thE3nigma]

Homework Statement

I did my lab work a week ago and in the lab report I am to discuss my results, and how successful. If not successful, then why not. Our Organic Chem. lab was on crystallization and we had to obtain pure Benzoic Acid crystals from 2 grams of a crude material.

My question is for such an experiment, what is usually considered a good percentage yield? Or should I discuss my success based on my own techniques and patience with the experiment?

If you have no idea about the composition of the crude material, you can't say anything about what is a good yield.

I see, that is what I was thinking. It is just that they asked for us to discuss the success of our experiments, but that is a general format for all labs in this course. I would assume I could just discuss based on my own ideas and thoughts.

Thanks by the way.
