Solution: Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produced 4.46 g of fluorine and 1.25 g of sulfur, while decomposition of a sample of sulfur tetrafluoride produced 4.44 g of fluorine and 1.87 g of sulfur.Calculate the mass of fluorine per gram of sulfur for the sample of sulfur hexafluoride.

Problem

Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produced 4.46 g of fluorine and 1.25 g of sulfur, while decomposition of a sample of sulfur tetrafluoride produced 4.44 g of fluorine and 1.87 g of sulfur.

Calculate the mass of fluorine per gram of sulfur for the sample of sulfur hexafluoride.

Solution

We’re asked to calculate the mass of fluorine per gram of sulfur for the sample of sulfur hexafluoride, SF6.


Since, we're given the mass of sulfur, S and the mass of fluorine, F for sulfur hexafluoride, we simply need to get their mass ratio
