Here's a calculator to see why you were wrong:

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.

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%

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 mass8.064/167.55*1.58=0.0760

The percent yield is determined as follows:

(actual/theory)*100=%yield

(0.0294/0.0760)*100=38.6%
