Tonicity: a measure of the osmotic pressure gradient (as defined by the water potential of the 2 solutions) of 2 solutions separated by a semipermeable membrane; commonly used when describing the response of cells immersed in an external solution; influenced only by solutes that can't cross the membrane, as only these exert an osmotic pressure; solutes able to freely cross the membrane don't affect tonicity because they will always be in equal concentrations on both sides of it

Question: What do you call a tooth in a glass of water? Answer: A one molar solution.  This is a chemistry joke. A Mole is a unit of measurement used in chemistry to express amounts of a chemical substance, defined as the amount of any substance that contains as many elementary entities as there are atoms in 12 grams of pure carbon-12, the isotope of carbon with relative atomic mass 12.
