At constant temperature and pressure, the volume of gas is directly proportional to the number of moles of the gas
At 0 degree Celsius and 1 atm, one mole of any gas will occupy the same volume, known as the molar volume of gas which is 22.4 L
The standard temperature and pressure is abbreviated to STP
Avogadro's Law
Can be used to determine the molecular mass and density of gas
Ideal Gas Law
Combines the three gas laws (Boyle's, Charles', and Avogadro's) into a single expression using the variables P, T, V and n, with R as the ideal gas constant
The ideal gas satisfies all assumptions of the kinetic moleculartheory
Any gas that obeys the three gas laws obeys the ideal gas equation and is known as an ideal gas
All gases are real gases, and under normal conditions like STP, the ideal gas equation works for most real gases because they behave like ideal gases
The ideal gas model fails at very low temperatures and very high pressure when the effect of intermolecular forces and particle size become significant
