i'v synthesized benzoic acid from benzyl alcohol and i have a theoretical value for the yield and and experimental yield of impure acid.

Theoretical Yield = 5.93g
Impure Yield from experiment = 6.13g

Now, my paper asks for the percentage yield of my impure acid, how does that work?

If i do:
6.13/5.93 x 100 then I am going to get a percentage yield of 103.4%

Is that right? surely i can get a yield greater than 100% ?

Later in the experiment it asks for the yield of pure acid which i have done with a reasonable %, i just don't understand it for the impure acid.

Your yield for a crude material can be anything... even >100%. You must explain (rationalize) the impurity in your discussion and suggest a method for its removal.
