a mole is a way to express how many particles there are. for example 1 mole of sand consist of 602 250 000 000 000 000 000 000 or 6.0225 × 1023 grains of sand. that's a lot, but if you're talking about atoms that is not so extremely much. for example 1 mole of table salt NaCl is only 58,44grams of salt.
why use mole and not grams?
I asked myself that same question, but some atoms are heavier then others and you will need more grams of it to have 1 mole, and so you can end up with very complex mathematics while you can just use moles.
an other example
2H² + O² --> 2H²O
this means that 2moles of hydrogen gas will react with 1 mole of oxygen gas to form 2 moles of water. this is very logical ^^ (for some people).
but in grams you need 4 grams of hydrogen 32 grams of oxygen and you will end up with 36grams of water.
okay it might sound more logical but look closely and you will see that oxygen gas is much heavier than hydrogen.
