Use the following atomic weights and quantities to calculate the overall % yield of 4-carboxamide-4'-pentyllbiphenyl. Remember that your yield must be based on the stoichiometry (Look back to the mechanism question for the correct stoichiometry of this reaction!), the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point.

Use the following atomic weights and quantities to calculate the overall % yield of 4-cyano-4'-pentyllbiphenyl. Remember that your yield must be based on the stoichiometry (balance the equation!), the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point.

C4H6O3 + H2NC6H4OH = C8H9NO2 + CH3COOH  Calculate the percent yield for this acetaminophen synthesis. Hint: This is a limiting reagent question. You'll have to calculate the theoretical yield of the product before you can find the percent yield.  We started with 0.321 g of 4-aminophenol.  At the end of the reaction, the product weighed 0.180 g.

Can i get help with this problem please

What is the overall % yield of triphenylmethane from benzophenone given the percentage yield of each step of the reaction sequence as follows? Give only two significant digits. If the answer is a whole number with two digits, do not include the decimal. 66% 70% 62% benzophenone → benzopinacol → benzopinacolone triphenylmethane Answer:

please answer this question, i think my calculations are coming out wrong- Calculate the theoretical yield and percent yield using the RESULT/DATA below: Mass of salicylamide: 0.503g Mass of sodium iodide: 0. 606 g  Mass of Recrystallized dry Product: 0.170g

I'm not sure how to go about calculating for percent yield of my product. Do I need to calculate theoretic yield first? I always mix up the formulas.  I was performing the horner wadsworth reaction , synthesis of 3,4-Methylenedioxystilbene. The reaction was between diethyl benzylphophonate and 3,4-dimethylenedioxybenzaldehyde. Aliquat 366 was the catalyst.
