To calculate the expected yield of nylon-6,6, we first need to determine the moles of adipic acid and then use the stoichiometry of the reaction to find the moles of nylon-6,6 produced. Finally, we can convert the moles of nylon-6,6 to grams.1. Calculate the moles of adipic acid:Adipic acid has a molecular formula of C6H10O4, and its molar mass is: 6 x 12.01 + 10 x 1.01 + 4 x 16.00 = 146.14 g/molGiven that we have 5 grams of adipic acid:moles of adipic acid = mass / molar massmoles of adipic acid = 5 g / 146.14 g/mol = 0.0342 mol2. Use the stoichiometry of the reaction:The reaction between adipic acid and hexamethylenediamine to form nylon-6,6 is a 1:1 molar ratio reaction. Therefore, the moles of nylon-6,6 produced will be equal to the moles of adipic acid reacted.moles of nylon-6,6 = moles of adipic acid = 0.0342 mol3. Convert the moles of nylon-6,6 to grams:Nylon-6,6 has a molecular formula of C12H22N2O2, and its molar mass is: 12 x 12.01 + 22 x 1.01 + 2 x 14.01 + 2 x 16.00 = 226.32 g/molmass of nylon-6,6 = moles x molar massmass of nylon-6,6 = 0.0342 mol x 226.32 g/mol = 7.74 gThe expected yield of nylon-6,6 is approximately 7.74 grams.
