Tenth graders learn about solutions — a solute dissolved in a solvent — and how to measure concentration with molarity (moles of solute per liter), the standard way chemists describe how strong a solution is.
Students will be able to…
A weak cup of tea and a strong one are both solutions — the difference is concentration. How do chemists precisely measure how much stuff is dissolved in a solution?
Project each item and have students answer about solutions and molarity. The tool explains solute, solvent, and the molarity formula.
