The law of mutliple proportions states that when two components combine to generate more than one compound, the combined weights of each element are in a ratio of tiny whole numbers. So, the correct answer is that there is a 2:1 ratio between the two compounds.
The law of multiple proportions states that a ratio of whole numbers exists between the masses of one element that combine with a set mass of the second element. This indicates that there is a 2:1 ratio between the masses of oxygen and carbon when they join.
Compound 1: 0.905 S/Cl.
Compound 2: 0.451 S/Cl.
