Avogadro’s law Equation / formula:
- P1 / n1 = P2 /n2.
- P1 n2 = P2 n1
- Where n is the amount of substance of the gas (measured in moles)
- V is the volume of the gas
Avogadro’s law Definition:
Definition of Avogadro’s law:
Avogadro’s law (sometimes referred to as Avogadro’s hypothesis or Avogadro’s principle) is an experimental gas law relating volume of a gas to the amount of substance of gas present. A modern statement of Avogadro’s law is:
Avogadro’s law states that, “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules”.
For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
