simplest way to relate reactants and products
Matter is made up of different kinds of particles. The term representative particle refers to whether a substance commonly exists as atoms, formula units or molecules.

4. Representative Particles
smallest particle of a substance that still retains the properties of that substance
1. ATOM: element
2. MOLECULE: covalent compound
3. FORMULA UNIT: ionic compound

5. MOLAR MASS Unit of measurement = g/mol
mass, in grams, of 1 mole of any substance
Unit of measurement = g/mol
