Answer is: a chemical formula of the compound is C₄Cl₄.

CCl is empirical formula of the compound. Empirical formula gives the proportions of the elements present in a compound, so we know that proportion od carbon and chlorine is 1 : 1 (n (C) : n (Cl) = 1 : 1).

M (CCl) = Ar (C) + Ar (Cl) · g/mol.

M (CCl) = 12.0107 + 35.453 · g/mol.

M (CCl) = 47.4637 g/mol; molar mass of empirical formula.

M (compound) = 189.86 g/mol; molar mass of the compound.

M (compound) / M (CCl) = 189.86 g/mol / 47.4637 g/mol.

M (compound) / M (CCl) = 4; chemical formula of the compound have four carbon and four chlorine atoms.
