Please note learners do not use the A11y View. Learners use the accessible simulation, alone, which is rendered here inside the iframe.
Molarity is an interactive sim. It changes as you play with it. It has a Play Area and a Control Area.
In the Play Area, you find a beaker containing a solution, and a concentration readout. You can change solute amount, solution volume, and choose from nine different solutes to play with the solution in beaker.
In the Control Area there is a checkbox to show exact values for amount of solute (in moles), volume of solution (in liters), and concentration (in molar), and a button to reset the sim.
Currently, beaker is half full of a red solution containing some drink mix solute. Solution is not saturated and has low concentration.
Play with solution in beaker and observe changes to concentration.
