How to solve problems that involve limiting reactants?

Introduction to the Limiting Reactant Lecture
The following video introduces the topic of Limiting Reactants.
Limiting Reactant Sample Problem 1
The following is a continuation of the video on the Limiting Reactant. In this video we look at solving a sample problem.
Example:
Lithium nitride reacts with water to form ammonia and lithium hydroxide. If 4.87g of lithium nitride reacts with 5.80g of water, find the limiting reactant.

Limiting Reactant Sample Problem 2
The following is a continuation of the video on the Limiting Reactant. In this video we look at solving another sample problem.
Example:
White phosphorus consists of a molecule made up of four phosphorus atoms. It burns in pure oxygen to produce tetraphosphorus decaoxide. A 1.00g piece of phosphorus is burned in a flask filled with 2.60 x 1023 molecules of oxygen gas. What mass of P4O10 is produced?
Limiting Reactant Example Problem 1
Example:
Methanol, CH3OH, which is used as a fuel in racing cars and in fuel cells, can be made by the reaction of carbon monoxide and hydrogen.
Suppose 356g of CO and 65.0h of H2 are mixed and allowed to react.
(a) What mass of ethanol can be produced?
(b) What mass of the excess reactant remains after the limiting reactant has been consumed?
