7. I can calculate or convert in any way between mass, moles, volume and representative particles (8 ways)
8. I can calculate the amount (count, mass or percent) of a given element with in a mass sample of a compound.
9. I can calculate molar density of a gas.
10. I can calculate the molecular formula from an empirical formula.
