The Mole

The Mole. "Not everything that counts can be counted, and not everything that can be counted counts." Albert Einstein. What is a mole?. The mole is a counting unit. Like . . . 1 dozen = 12 each 1 yard = 3 feet 1 cup = 8 ounce So then ... 1 mol = 6.022 x 10 23 particles

Ch 7.3 Using Chemical Formulas

Ch 7.3 Using Chemical Formulas. The Mass of a Mole of an Element. Remember: The atomic mass of an element (a single atom) is expressed in atomic mass units (amu). Molar Mass: is the atomic mass of an element expressed in grams/mole (g/mol). Carbon = 12.01 g/mol Hydrogen = 1.01 g/mol
