Mole is abbreviated to mol and given the symbol n
1 mole contains the same number of particles as there are in 12g of carbon-12 atoms by definition.
This number is called Avogadro's number or Avogadro's constant (NA) and is equal to 6.022 x 10 23 particles.
1 mole of a pure substance has a mass in grams equal to its Relative Atomic Mass (RAM) or its Relative Molecular Mass (RMM) [also known as molecular weight (MW) or Relative Formula Mass (RFM) or formula weight (FW)].This is often referred to as the molar mass.
1 mole of an ideal gas has a volume of:
22.4 litres (22.4L) at S.T.P.
[Standard Temperature and Pressure, 0 oC (273K) and 101.3kPa (1 atm)]
24.47 litres (24.47L) at S.L.C
[Standard Laboratory Conditions, 25 oC (298K) and 101.3kPa (1atm)]
Avogadro's Number (NA)
1 mole of atoms or molecules contains 6.022 x 10 23 atoms or molecules
