**Law of Multiple Proportions** (Dalton):
- Definition: If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of **small whole numbers**.
- Example: In $CO$ ($12 	ext{ g } C$ with $16 	ext{ g } O$) and $CO_2$ ($12 	ext{ g } C$ with $32 	ext{ g } O$), the ratio of masses of oxygen combining with $12 	ext{ g } C$ is $16:32$, which simplifies to **1:2** (simple whole numbers).
