WebA convenient amount unit for expressing very large numbers of atoms or molecules is the mole. Experimental measurements have determined the number of entities composing 1 mole of substance to be 6.022 × 10 23, a quantity called Avogadro’s number. The mass in grams of 1 mole of substance is its molar mass. WebThe MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 10 23 ). So the mole is the title used for the amount 6.022 x 10 23 much the same way the word "dozen" is used for the amount 12.
