What Is Avogadro

WebIn 1811, Italian physicist and mathematician Amedeo Avogadro published a hypothesis (also termed Avogadro's law or principle) stating that the volume of a gas is directly proportional to the number of molecules of the gas. This is represented by the formula. where a is a constant, V is the volume of the gas, and N is the number of gas molecules. WebThe value of Avogadro's number was obtained by dividing the charge of a mole of electrons by the charge of a single electron which is equal to 6. 02214154 × 10 23 particles per mole.
