Avogadro’s Law
❖ Amadeo Avogadro (1776-1856) proposed that equal volume of gases at the
same temp pressure contain the same number of particles regardless of their
chemical nature and physical properties
❖ The balloons all have the same volume. This means they all contain the
same number of molecules
❖ One mole of any gas consists of 6.02x10^23 particles, a number known as
Avogadro’s number
❖ It is the number of particles of any gas present in 22.4 L at STP
❖ This volume is referred to as the molar volume of gas
❖ Avogadro’s law states that the equal volume of gases at the same temp and
pressure contain equal numbers of molecules
❖ It also means that the has volume is directly proportional to the number of
moles of gas temp and pressure ❖ One mole of substance contains
6.02x10^23 particles
❖ V1/n1=V2/n2
❖ Sample 1
➢ A 10 moles of carbon dioxide gas has a volume of 245L at 25C and 1
atm pressure. If 5 moles of the carbon dioxide is removed at the same
temp and pressure, what volume will the gas now occupy?
➢ Solution:



❖ Sample 2
➢ A balloon has been filled to a volume of 1.90L with 0.0920 mol of
helium gas. If 0.0210 mol of additional helium is added to the balloon
while the temp and pressure are help constant what is the new volume
of the balloon?
➢ Solution:




❖ Applications
➢ Breathing
➢ Inflating balloon
➢ Inflating tyres
