Avogadro's Number (symbol

<math>N_A</math>)
The number of molecules in 1 mole of gas (<math>6.02252 X 10²³</math> per mole).
That this number is a constant for permanent gases is the Avogadro law: under normal conditions, i.e., pressure of 1 standard atmosphere and temperature of 0° C, the volume occupied by 1 mole of gas is the same for all permanent gases (22,414 cubic centimeters). See Loschmidt number. [[/A>|/A>
