Interpretation Introduction

Interpretation:

The key term that corresponds to the definition “the statement that equal volumes of gases, under the same conditions of temperature and pressure, contain equal numbers of molecules” is to be stated.

Concept introduction:

A mole is the amount of substance that has Avogadro’s number of particles. The Avogadro’s number is $\text{6}\text{.02}\times {\text{10}}^{\text{23}}$. Mathematically, the mole is the ratio of the mass and the molecular mass of the substances.

$\text{Mole}=\frac{\text{Mass}}{\text{Molecular mass}}$

One mole of atom or molecule is equal to $\text{6}\text{.02}\times {\text{10}}^{\text{23}}$ particles.
