Question

Prove ( by forming appropriate ratios) that the following four oxides of sulfur obey the Law of Multiple Proportions. There are a total of six seperate and distinct ratios taht can be formed from this data. This does not include any inverses of these ratios.

S2O
SO2
S2O3
SO3

Answer 1

Atomic weights: S=32 O=16 S2O=80 SO2=64 S2O3=112 SO3=80

80:64:112:80::5:4:7:5

The molecular weights are to one another as the ratio of small whole numbers.
