# How did Avogadro determine the mole?

Contents

The term “Avogadro’s number” was first used by French physicist Jean Baptiste Perrin. … If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.

## What is Avogadro’s number How does it relate to the mole?

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 mol1 and is expressed as the symbol NA.

## Why did Avogadro call it a mole?

(c) Avogadro’s number is often the denominator in mathematical equations, so it was given the name the mole to describe its burrowing characteristics. (d) Two different people, Avogadro and Mole discovered the number at the same time, therefore they share its name.

## What order did Avogadro discover the mole?

He was the first to make a distinction between molecules of a substance and its atoms. From Avogadro’s law, it follows that one molar volume of any gas contains the same number of molecules, 6.02252 × 1023, now called Avogadro’s number–or a mole.
