Sorry, you're wrong! Better luck next time!
The answer was: 38.6%
To answer this question, you use the mass ratio from the balanced equation to determine the theoretical yield.
theoretical yield of H2:(mass of H2)/(mass of Fe)*given mass
8.064/167.55*1.58=0.0760
The percent yield is determined as follows:
(actual/theory)*100=%yield
(0.0294/0.0760)*100=38.6%
