Question

Sulfur forms two compounds with fluorine. In one of them 0.447g of sulfur is combined with 1.06g of fluorine and in the other 0.438g sulfur is combined with 1.56g of fluorine. Prove that these data illustrate the Law Of Multiple Porportions?

Answer 1

The law of multiple proportions:
"If two elements form more than one compound
between them, then the ratios of the masses of the second element which combine
with a fixed mass of the first element will be ratios of small whole
numbers".
The ratio of the masses of fluorine that combined with almost the
same mass of sulfur (ca.0.440 g) is 1.56:1.06 ≈ 1.5:1 ≈ 6:4, a ratio of small
whole numbers.
(the compounds are SF6 and SF4 respectively)
