Question

Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produces 4.43 g of fluorine and 1.25 gof sulfur, while decomposition of a sample of sulfur tetrafluoride produces 4.45 g of fluorine and 1.88 gof sulfur.

what is the mass of fluorine per gram of sulfur for the sample of sulfur hexafluoridea?

what is the mass of fluorine per gram of sulfur for the sample of sulfur tetrafluoride?

Answer 1

the mass of fluorine per gram of sulfur for the sample of sulfur hexafluoride is

32 gm of sulfur formed.....................from 146gm of sulfur hexafluoride

1gm of sulfur.............................?

     = 146/32 = 4.562gm of sulfur hexafluoride

for146gm of sulfur hexafluoride.............................3*38 gm of F2

4.562gm of sulfur hexafluoride.................................?

      = 3*38*4.562/146 = 3.561 gm of F2

....................................................................................

the mass of fluorine per gram of sulfur for the sample of sulfur tetraafluoride is

32 gm of sulfur formed.....................from 108.05gm of sulfur tetrafluoride

1gm ofsuulfur.............................?

     = 108.05/32 = 3.376gm of sulfur tetrafluoride

for108.05gm of sulfur tetrafluoride.............................2*38 gm of F2

3.376gm of sulfur tetrafluoride.................................?

    = 2.374 gm of F2
