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 im 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 dont understand it for the impure acid.
