13. Define the Law of Definite Proportions:
In any sample of ONE compound, the masses of the elements are always in the same proporations
14. Define the Law of Multiple Proportions
Whenever two elements form MORE THAN ONE compound, the masses of the elements in the
compounds combine in whole number ratios.
