At a temperature of 450 °C and 200 atmospheres the actual mass of ammonia produced
when 1000 g of nitrogen is passed through the reactor is 304 g.
Calculate the percentage yield of ammonia produced in the reactor.
(If you did not answer part (a), then assume that the maximum mass of ammonia that can
be made from 1000 g of nitrogen is 1100 g. This is not the correct answer to part (a).)
