Explain terms of Avogadro constant, molecules volume of 1 mole gases,STP. |
|
Answer» SOLUTION :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. |
