But wait, what actually is a mole? The mole is the SI unit of the measurement for the amount of a substance. In one mole of matter, there is precisely 6.02214085774 × 10²³ (using scientific notation) atoms, molecules, or anything else. This tremendous value refers to Avogadro Gramov na mol (g/mol - Molárna hmotnosti jednotky), molárna hmotnosť Do textového poľa zadajte číslo Gramov na mol (g/mol) , ktoré chcete previesť, aby ste v tabuľke zobrazili výsledky. Krtek - vo výpočtoch skrátene mol, je jednotka chémie používaná na vyjadrenie malej hmotnosti ľubovoľného typu častice od atómu k molekule. Jeden mól akejkoľvek častice je ekvivalentný k jej atómovej hmotnosti, uvádzanej ako u alebo gramy na mól, ako je uvedené v periodickej tabuľke.

(valency of Zn, Mg, Fe = 2). (2) Molecular mass : Molecular mass of a molecule, of an element or a compound may be defined as a number which indicates how many times 1 heavier is a molecule of that element or compound as compared with of 12 the mass of an atom of carbon–12. Molecular mass is a ratio and hence has no units.
