Problem

An iron nail rusts when exposed to oxygen. 

For the following reaction,  5.71 grams of iron are mixed with excess  oxygen gas. The reaction yields 7.36 grams of  iron(III) oxide

iron (s) + oxygen (g) → iron(III) oxide (s) 

a) What is the theoretical yield of  iron(III) oxide

b) What is the percent yield for this reaction ?
