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. WebView full document.
