A student reacts steel wool with oxygen by touching the fibers with a 9 volt battery. They begin
with 7.93 g Fe and measure the mass of the final product at 9.50 g.
The balanced equation for the reaction is:
2 Fe + 02 --> 2 FeO
A) The student claims that the percent yield of the reaction was 93.1 %. Support or reject their
claim including a calculation of percent yield as part of your evidence.
