Can you give me all formulas related to Mole Concept, in chaper Atoms and molecules
One mole of any substance contains a fixed number (6.022 � 1023) of any type of particles (atoms or molecules or ions) and has a mass equal to the atomic or molecular weight, in grams. Thus it is correct to refer to a mole of helium, a mole of electrons, or a mole of Na+, meaning respectively Avogadro�s number of atoms, electrons or ions.
Number of moles = Weight (grams)/Weight of one mole (g/mole)
= Weight/Atomic or molecular weight
