Overview

The mole concept gives a practical way to count extremely small particles such as atoms, molecules and ions. Just as a dozen means 12 objects, one mole means 6.023 × 10^23 particles. This idea connects atomic mass, molecular mass, volume of gases, and chemical equations, making it possible to calcul

Key Concepts

When two or more gases react

When two or more gases react together, their volumes bear simple whole number ratio with one another and to the volume of products, if they are also g

Under identical conditions of temperature

Under identical conditions of temperature and pressure, equal volumes of all gases contain equal number of molecules. This explains why gas volume dep

A mole is the amount

A mole is the amount of any substance which contains as many elementary entities as there are atoms in 12 g of C12. Avogadro's number is 6.023 × 10^23

At STP

At STP, the volume of 1 mole of gas is 22.4 litre. SATP refers to 1 bar pressure and 25°C or 298 K, where 1 mole of gas occupies 24.78 litre.

The molar volume of a gas

The molar volume of a gas is the volume occupied by one mole of the gas at STP. It is 22.4 litres at STP.

Learning Objectives

  • Understand the meaning of mole and Avogadro's number
  • Use Avogadro's law and Gay Lussac's law for gases
  • Relate molar mass, gram atomic mass and gram molecular mass
  • Calculate molecular mass and relative atomic mass on the C12 scale
  • Distinguish empirical formula from molecular formula
