How many atoms per molecule
WebMay 3, 2024 · What is the number of atoms of an element present in one molecule of a substance? The number of atoms or other particles in a mole is the same for all substances. The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 1023 atoms and a mass of 12 grams. WebChemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole (abbreviated mol) is equal to 6.022×10 23 molecular entities (Avogadro’s number), and each element has a different molar mass depending on the weight of 6.022×10 23 of its atoms (1 mole).
