This is a power point that covers one of the most difficult concepts in chemistry for students, stoichiometry. Color is used to help students place the many conversion factors in the correct boxes, on the molar highway, also known as the factor label method. Four stoichiometry problems are addressed in detail. The four conversion problems included are Mass-Mass, Volume-Mass, Mass-Avogadro's Number, and Mass-Energy. There are 3 slides that contain blank boxes for students to use when solving any and all stoichiometry problems.
