* Densities of the two reactants are: Sebacoyl chloride 1.121 g/mL and, 1,6-diaminohexane 0.83 g/mL
We know
density = mass/ volume
mass = density * volume
Mass of Sebacoyl chloride = 1.121 g/mL * 2ml = 2.242g
Mass of 1,6-diaminohexane = 0.83 g/mL* 1.3ml = 1.079g
molar mass of 1,6-diaminohexane =116.21 g/mol
molar mass of Sebacoyl chloride = 239.14g/mol
molar mass of nylon 6,10 = 318.458 g/mol
According to reaction;
239.14g of Sebacoyl chloride reacts with 116.21 g of 1,6-diaminohexane
so, 2.242g of Sebacoyl chloride reacts with = (116.21/239.14)2.242 g of 1,6-diaminohexane
= 1.09g of 1,6-diaminohexane
as only 1.079g of 1,6-diaminohexane is taken, hence 1,6-diaminohexane is limiting reagent.
now , according to reaction ; Theoritical yield of nylon 6,10 is:-
116.21 g of 1,6-diaminohexane gives = 318.458 g of nylon 6,10
so, 1.079g of 1,6-diaminohexane will give = (318.458 g /116.21 g) * 1.079 g of nylon 6,10
= 2.96g of nylon 6,10
percent yield = (experimental yield/Theoritical yield ) *100
= (3.30/2.96) * 100
= 111.5%
but it is practically not possible,
practical yield can never be more than that of theritical yield.
hope this is helpful!
