QUANTITATIVE CHEM
Concept of Mole
1 mole: the amount of substance that contains the same number of particles as the number of atoms in 12g of 12C.
Avogadro Constant: The amount of particles in 1 mole of any substance.

1 mole ≡ 6.02 × 1023 particles

Isotopes
Isotopes: Atoms that have the same number of proton but different number of neutrons.
 Isotopes have similar chemical properties but different physical properties.

Ar =

Avogadro’s Law
1 mole of gas would fill up:
 22.4 dm3 at STP (273K and 1atm)
 24.0 dm3 at room condition (298K and 1atm)
