The law of proportion states that elements combine in whole number ratios. The gram readings for K are multiples of each other, both in grams and moles.

Let us compare the ratios:

2.44 grams/1.22 grams = 2

4.89 grams/2.44 grams = 2

Therefore, Potassium always combines with Oxygen in a ratio of 2 is to 1.
