Question

38. Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produces 4.45 g of fluorine and 1.25 g of sulfur, while decomposition of a sample of sulfur tetra- fluoride produces 4.43 g of fluorine and 1.87 g of sulfur. Calcu- late the mass of fluorine per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportions.
