Explain terms of Avogadro constant, molecules volume of 1 mole gases, STP.

Explanation

Avogadro constant : 1 mole gas contain `6.22 xx 10^(23)` molecules is known as Avogadro constnat.
1 mole : According to mole concept 1 mole means `6.22xx10^(23)` particles. (Atom, molecule electron …..)
Molecules volume OR Molar volume `(22.71084 = mol^(-1))` : According to Avogadro principle, volume of gas `(V)prop` mole of gas number (n) STP temperature and pressure 1 mole gas occupy or molecular volume.
At STP molar volume ideal gas on a combination of ideal gases is 22.71098 L `mol^(-1)`. It is also known as molar volume.
Meaning of STP : Standard temperature and pressure means `273.15 K (0^(@)C)` temperature and 1 bar (exactly `10^(5)` Pascal) pressure. These values approximate freezing temperature of water and atmospheric pressure at sea level.
