The+Mole+and+Formulas

Atoms are tiny and there are A LOT of them out there! To make our work a little easier, we group atoms (and molecules and anything else sufficiently small) into a a counting group called the //mole//. With the mole, we can tie the invisible and impossibly tiny world of atoms and molecules to our macroscopic world of tangible objects we can weigh and hold. In this unit, we will learn to convert from numbers of particles to moles and then to mass. We will also use the masses and moles of elements in compounds to determine the //empirical// and //molecular formulas// of compounds.
