Molarity Practice Problems Stoichiometry by the Recipe Mole Quiz The Mole Lecture Notes

It is difficult to imagine such a large number as Avogadro's number. Some idea of its magnitude is given by the following calculation. Let us suppose that the entire state of Texas, with an area of 262,000 square miles, were covered with a layer of fine sand 50 feet thick, each grain of sand being 1/100 of an inch in diameter. There would then be Avogadro's number of sand particles in this immense sandpile. There would be the same number of molecules of water in one mole of water -- 18g, 1/25 of a pint.
