Topic 3: The Mathematics of Formulas and Equations

The sum of the atomic masses of atoms in the empirical formula of the compound in amu.

Formula mass expressed in grams

Percentage by mass of each element in a compound. (on reference table)

6.02 * 10^23

Equal volumes of gasses at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties -22.4 L of any gas at STP contains one mole of that gas

# of Moles * Gram Mass Formula/ 1 mol Mole ratios from a balanced equation will remain the same (On reference table)
