Question

The aspirin substitute acetaminophen (C8H9O2N) is produced by the following three-step synthesis:
I. C6H5O3N(s) + 3H2(g) + HCl(aq) → C6H8ONCl(s) + 2H2O(l)
II. C6H8ONCl(s) + NaOH(aq) → C6H7ON(s) + H2O(l) + NaCl(aq)
III. C6H7ON(s) + C4H6O3(l) →C8H9O2N(s) + HC2H3O2(l)
The first two reactions have percent yields of 87% and 98% by mass, respectively. The overall reaction yields 3 moles of acetaminophen product for every 4 miles of C6H5O3N reacted.
a. What is the percent yield by mass for the overall process?
b. What is the percent yield by mass of step III?
