Definition of Avogadro’s Law

Definition of Avogadro’s Law :“the equal volumes of all gases have equal number of moles” under standard conditions of temperature and pressure.

Standard temperature is 273 K or 00 Celsius

Standard Pressure is 100 kPa

Thus 1 mole of each gas at 273 K temperature and 100 kPa pressure,  will have 22.7 dm3.

22.7 dm3 is called molar gas volume.

Numerically Volume V is directly proportional to number of moles.

V ∝ n

V=kn where k is proportionality constant.

Example:

1 mole of O2 and 1 mole of CO2 will have 22.7 dm3 volume at 273 K temperature and 100 kPa pressure. 6.02X1023
