Acompound contains 30. percent sulfur and 70. percent fluorine by mass. the empirical formula of the compound is

The empirical formula of the compound is: SF₄

The empirical formula of a compound is an expression of the formula of the compound in its simplest form showing the ratio of the atoms of the different elements present in the compound.

The empirical formula of the compound given in the question above can be obtained as follow:

Sulphur (S) = 30%

Fluorine (F) = 70%

S = 30%

F = 70%

Divide by their molar mass

S = 30 / 32 = 0.9375

F = 70 / 19 = 3.6842

Divide by the smallest

S = 0.9375 / 0.9375 = 1

F = 3.6842 / 0.9375 = 4

Therefore, the empirical formula of the compound is SF₄
