Moles of an element = Mass of the element Atomic mass or GA.W
|
Moles of a compound = Mass of the compound Molecular mass or GMW
|
Mass of one atom = Atomic Mass or GAW 6.022 × 1023
|
Mass of one molecule = Molecular Mass or GAW 6.022 × 1023
|
Number of molecules = Moles × 6.022 ×1023
|
Number of atoms = Moles × 6.022 ×1023
