Avogadro's hypothesis site not working :(
What is a mole: The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of 12C. Fundamental units may be atoms, molecules, or formula units, depending on the substance concerned. An amount of any chemical compound that is equal to the combined atomic weights or the molecular weight, expressed in grams, contains 602,213,670,000,000,000,000,000 molecules.
Hey Bridget, it's Dmitrius. A mole is an Avogadro's number of anything. You can have a mole of toothpicks, or a mole of peanuts, as well as a mole of water molecules. Hope that clarifies a bit. Cheers
