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 tetrafluoride produces 4.43 g of fluorine and 1.87 g of sulfur. calculate the mass of fluorine per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportion.
