All chemists know that moles are made of molecules. Individuals see how changes in the amount of solute affect the concentration of the solutions. By manipulating solute amounts (moles), solution volume (liters), and solute types, the solution concentration (molarity) adjusts reflecting these changes.

Instructional Ideas

• Project the simulation to the class and use during discussion on molarity; ask for predictions for concentration or mole values and then click to show

Classroom Considerations

• Related lessons, teacher tips, and video primer are accessible to teachers who set up a free account
• Assumes class members understand moles and molarity

Pros

• Simulation is simple and easy to use
• Can be viewed in a number of different languages

Cons

• None
