Avogadro's law is applicable anly at high temperature and low pressure (to an ideal gas). Then why molar volume is calculated at stp(0degree celsius and 1 atm pressure, that is low temperature and high pressure), when gas does not behave ideally? Is the molar volume of 22.414litres merely hypothetical?

Dear deeksha,

For an ideal gas two conditions are necessary, 1- its molecules should volume less and 2- there is no force of attraction among its molecules, both these conditions are impossible to full fill therefore an ideal gas does not exists.
