That lets them figure out how much chemical is needed for a reaction since the balanced equation shows how many moles of one chemical react with each mole of another chemical. If you put in too little all of the original can not participate in the reaction. If you put in too much then the extra unused chemical is in there with the desired products.

A mole contains the same number of molecules whether they are big and heavy or small and light. This lets chemists measure ingredients for an experiment in a way that corresponds to the molecules in their balanced equations.
To use a non-chemistry analogy, let's say you wanted to make a necklace with a repeating pattern of red, yellow, green, and black, but each type of bead is a different size/weight. If you bought packages of beads with the same number of beads, the packages would be different sizes but you would have enough of each color. If you bought packages of beads that were the same weight but different numbers of beads, then you'd run out of the big ones first and have a lot of small ones left over.

It shortens a extensive style so which you do no longer could write an extremely super extensive style on an undemanding sized paper. 6.022 situations 10^23 is extra extra suitable than writting the particularly extensive style which may well be 6.022000000000000000000000
