Consider the following reaction.
4Fe + 3O2=2Fe2O3
a. How many moles of O2 are required to react completely with 29.8 mg of Fe?
4.00 x 10^-4 moles O2
b. How many grams Fe2O3, are produced from the complete reaction of 17.8 g of Fe?
25.4 g Fe2O3
right. So why did you have a problem with the earlier post?
