When iron rusts in air, iron(III) oxide is produced. How many moles of oxygen react with 2.4 mol of iron in the rusting reaction?
Meg--All of these stoichiometry problems are worked alike. I gave you the equation for iron and oxygen in the example I worked. The problem gives you mols so you don't need step 2 to convert grams to moles; that has been done for you.
