  4. So what I gathered from everybody's eles posts mixed in with some of my own thoughts give me this explanation: A mole is a unit of mass to simplify a chemical equation, meaning I wanna know how much this chemical equation is in one number. So I'll take the mass of the element and multiply it by the number of times the element occurs and add it all up depending on how the chemical equation is set up.

    A mole is the amount of a substance that contains 6.02*10^23 representative particles of that substance. Moles are important to chemist because moles give you a way of determining the ratio of the number of atoms of an element.
