Sulfur reacts with fluorine to produce three different compounds. The mass ratio of fluorine to sulfur for each compound is given in the following table:

Compound mass F : mass S

S2F10 2.962

SF4 2.370

SF6 3.555

Show that these data are consistent with the law of multiple proportions.

Mass of F / Mass of S = 2.962/1 = 2.962 X 32 / 32 = 94.78/32

Mass of F / Mass of S = 2.370 / 1 = 2.370 X 32 / 32 = 75.84 / 32

Mass of F / Mass of S = 3.555/1 = 3.555 x 32 / 32 = 113.76 / 32.

Now constant mass of S that is 32 g reacts with different mass of F. They are as follows:

94.78 g, 75.84 g, and 113.76 g

Their ratio = 94.78 : 75.84 : 113.76

divide them by 19

their ratio = 5 : 4 : 6

So these data are consistent with law of multiple proportion.
