    The actual yield is only 330 kg so that the fractional yield is In multi step processes it is important that each step have as high a percentage yield as possible The reason for this is that the overall percentage yield will be a product of the percentage yields of each stepTHE per hectare yield of major crops like wheat rice cotton sugarcane and maize is lower than the potential A number of factors could be attributed to low crop yield in the country

    In chemistry yield also referred to as reaction yield is the amount of product obtained in a chemical reaction The absolute yield can be given as the weight in grams or in moles molar yield The percent yield of the aspirin obtained from the experiment is 463 yield The higher the yield percentage the higher the purity of the aspirin will be Therefore according to the results the aspirin obtained is relatively impure However the low percent yield can also mean that the reactant has not reacted completely or the reaction is not complete However there is also another

    Actual yield is the amount of product produced in the experiment so if you re actually doing a lab and you re doing the experiment on your own it s the actual amount of product that you actually formed in the lab you as the student or you as a Chemist actually have produced The theoretical yield is a maximum produced through calculations so you re not Superman you re going to make mistakes It is very possible that the low percent yield for the purified product was caused by such a side reaction Also if there was less Grignard reagent added then less product would form and it will stop the formation of product during the benzophenone intermediate step of the reaction
