why do we use the mole?
so its easier to do chemical reactions, because you can group atoms into easier to measure groups

100
how do you calculate molar mass?
add together all the molar masses of your elements that make up the compound

what is a catalyst?
something that speeds up the rate of a reaction, but is not totally necessary for a reaction to occur
