There are two different compounds of sulfur and fluorine.
in sf6, the mass of fluorine per gram of sulfur is 3.55 g f/g s.
in the other compound, sfx, the mass of fluorine per gram of sulfur is 1.18 g f/g s.
what is the value of x for the second compound?
express your answer as an integer.

is there multiple choice answers?

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
