Question 8. In 1869 John Wesley Hyatt produced a plastic substance he named celluloid. Cellulose nitrate, or celluloid, was used as a substitute for ivory and used in the manufacture of a variety of items ranging from billiard balls to movie film. Cellulose nitrate is extremely flammable, however, and it has been replaced by other plastics for almost all uses except Ping- Pong balls. Calculate the average molecular weight of the polymer chains in the cellulose nitrate in Ping-Pong balls if the formula for the monomer is CoH9NO7 and the average polymer chain contains 1500 monomers.
