When 16.3 g of magnesiumm reacts with 4.52 g of oxygen, how many grams of magnesium oxide will be performed? Identify the limiting and excess reactants.

Answer 1

Do you know how to solve simple stoichiometry problems; i.e., say 16.4 g Mg and all of the oxygen you need (instead of an amount listed). If you do the limiting reagent problem is a quick switch. Here is an example of a simple stoichiometry problem.
