Answer to Question #51490 in Organic Chemistry for Carlos

Question

Hexamethylenediamine (C6H16N2) is one of the starting materials for the production of nylon. It can be prepared from adipic acid (C6H10O4) by the following overall reaction:
C6H10O4 (l) + 2NH3(g) +4h2(g) --> C6H16N2(l) + 4H2O(l)

a) what mass of Hexamethylenediamine can be prepared from 1 x 10^3 of adipic acid?
b) what is the percent yield if 765g Hexamethylenediamine is made from 1 x10^3 adipic acid?

Answer 1

a) This can be observed from the equation that from 1mole of adipic acid 1mole of Hexamethylenediamine will be formed, so the mass of Hexamethylenediamine will be 1 x 10^3, or 1000g.
b) The percent yield will be: (765g/1000g)*100% = 76.5%
