He didn't. Avogadro's number was simply named after Avogadro.
No! Avogadro just guessed the average number of molecules,ions,atoms number in one mole of any compound,element,etc.
Avogadro's number is the number of particles - atoms or molecules - in one mole of the element or compound.
the number 6.022 times10 to power 23 is Avogadros LAW HELP IN CALCULATIONS AND ITS REPRETATIONS
A mole contains an avogadros number of molecules, formula units for chemical compounds or atoms for elements.
Avogadro's number of any particles or countable objects, equals by definition 1 (exact) mole.
The words for the Avogadro law are:equal volumes of all gases, at the same temperature and pressure, have the same number of molecules
The Avogadro law is: equal volumes of gases, at the same temperature and pressure, have an equal number of molecules.
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
Molar mass is expressed in kg/mol or g/mol.The Avogadro number is 6,o22 140 857(74).10e23/mol.
The number of atoms in one mole is given by Avogadros number. This is: Avogadro's number = 6.0221415 × 1023 atomsTherefore, two moles of a substance contain 1.2044283 x 1024 atoms
