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?
