Why are chemists great for solving problems? They have all the solutions. Introduce your young chemists to the various ways of describing solutions, including molarity, molality, and mass percent, with a video that also explains why polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes. Henry's Law is also discussed.
