Avogadro’s constant (often called Avogadro’s number) defines the number of particles of a substance, such as atoms, molecules, or ions, that make up a mole. Avogadro’s number is 6.02214076 × 1023.[1] Avogadro’s constant is so large that it’s almost always referred to usingscientific...

mole. Usually, moles refer to particles that make up a certain amount of an element, and we use moles to measure how much of a substance is reacting in a chemical equation. However, you can also measure other things in moles—for example, a mole of hippos would be 6.02×1023 hippos ....
Moles The smallest unit of matter with unique properties is an atom. Atoms are too small to use for measurement in experiments. 6.02 x 1023 atoms = 1 mole Moles con’t The mass of 1 mole of an element can be found on the periodic table. Atomic mass or atomic weight =# of grams in...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
