Answer :
If 22 g acetaminophen (151.163 g/mol) was generated. The percent yield of the reaction is 72.78 %.
Calculation :
C₆H₇NO + C₄H₆O₃ --> C₃H₉NO₂ + C₂H₄O₂
0.20 moles 0.25 moles 22g
limiting reagrnt --> C₆H₇NO
from reaction equation
.20 mol of acetaminophen = .20*151.163 = 30.23 g
% yield = (practical/ theoritical)yield* 100 = 72.78 %
reaction yield. The reaction yield (absolute yield) of a chemical reaction is the amount of pure, dry product recovered from the reaction. Relative yield or percent yield (%) is commonly calculated to measure the efficiency of chemical reactions in organic synthesis.
Yield, also called reaction yield, is a measure of the molar amount of product to reactant consumed in a chemical reaction, usually expressed as a percentage. Yield is one of the main factors that scientists must consider in organic and inorganic chemical synthesis processes. [2] In chemical reaction engineering, “yield,” “conversion,” and “selectivity” relate to unwanted products, how much of the starting material is consumed (conversion), how much of the desired production A term used to describe the rate at which something is formed (yield). (selectivity) represented as X, Y, and S
