how to find how many pairs of lone pair in a molecule?
-
You would draw the covalent bonding (shared pair of electrons between atoms) and what ever is left are the lone pair of electrons.
for example in water:

This molecule has 2 pairs of lone pairs of electrons (those not involved in bonding).
Hope this helps :)
