Question

What is Avagadro's Number?​

Answer 1

Note:-

• Constant and Number both are same

Solution:-

✭ The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample.

✭ Its SI unit is the reciprocal mole, and it is defined as NA = 6.02214076×10²³ mol⁻¹.

✭ It is named after the Italian scientist Amedeo Avogadro

Answer 2

Answer:

The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined as NA = 6.02214076×10²³ mol⁻¹. It is named after the Italian scientist Amedeo Avogadro.

physicist Jean Baptiste Perrin

The term “Avogadro's number” was first used by French physicist Jean Baptiste Perrin. In 1909 Perrin reported an estimate of Avogadro's number based on his work on Brownian motion—the random movement of microscopic particles suspended in a liquid or gas.

Molar mass

Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
