Answer:

CF₄

Explanation:

CFx where x stands for a whole number.

According to the measurements of a certain sample, the molar ratio of fluorine to carbon is 8.5:2.11. We can use this ratio to calculate "x", considering there is 1 mole of carbon in the chemical formula of CFx.

1 mol C × (8.5 mol F/2.11 mol C) = 4 mol F

The chemical formula is CF₄.
