Dear student!

Sorry, but you haven't mentioned the anything related to your question. You didn't tag any topic or subject too. So, it's quite difficult to predict, on what regards did you ask the question. If it is regarding the chemistry organic practical of preparation of compounds, then percentage yeild is calculated as ( experimental yeild divided by theoretical yeild ) multiplied by 100.

Hope this helps.

Good luck!

Hi Rangaiah!! Hope you are doing well!! There is a simple formula to find percentage yields of many problems. First you habe to find the actual yield and then the theoretical yield and after that, apply the given formula to calculate the percentage yield -

Percentage yield= (actual yield/theoretical yield)*100
