Mole Island Graphic Organizers

The Mole Island graphic organizer depicts the relationships between the various stoichiometry quantities. The graphic is based on the generic reaction between reactants A and B and products C and D. The coefficients in the balanced equation are w, x, y, and z. The question of what is related to what? and how are they related? is addressed by the arrows on the diagram. There is a direct relationship between any two quantities connected by arrows. The manner in which they are related – either by molar mass values or coefficients – is written next to the arrow.

You can learn more about the Mole Island Graphic Organizer in our Stoichiometry Tutorial.

While the Generic Reaction will have a detailed description for visually impaired, the other example reactions will not.

Ammonia Synthesis Reaction

A diagram illustrates the stoichiometric relationship between nitrogen (N₂), hydrogen (H₂), and ammonia (NH₃) in a chemical reaction, using mole islands to represent grams and moles for each substance.

Titanium(IV) Nitride Synthesis Reaction

A diagram illustrating the stoichiometric relationships between titanium (Ti), nitrogen gas (N₂), and titanium nitride (Ti₃N₄) through mole islands representing grams and moles, connected by arrows.

Titanium(III) Oxide Synthesis Reaction

A flowchart visualizes the stoichiometric relationships in the reaction 4 Ti(s) + 3 O_2(g) to 2 Ti_2O_3(s) using the Mole Island chart.

Water Synthesis Reaction

A chemical reaction diagram shows the relationship between grams and moles of hydrogen, oxygen, and water using mole island.

Methane Combustion Reaction

A diagram illustrating the stoichiometric relationships between methane (CH₄), oxygen (O₂), carbon dioxide (CO₂), and water (H₂O) in a chemical reaction, organized using the concept of "islands" (CH₄ Island, O₂ Island, CO₂ Island, and H₂O Island) connected via Mole Island.
