To find the percent composition of the compound, we first need to determine the molar mass of the empirical formula CCl.Molar mass of Carbon  C  = 12.01 g/molMolar mass of Chlorine  Cl  = 35.45 g/molMolar mass of CCl = 12.01 g/mol  C  + 35.45 g/mol  Cl  = 47.46 g/molNow, we need to find the ratio between the molar mass of the compound  98.96 g/mol  and the empirical formula  CCl, 47.46 g/mol .Ratio =  Molar mass of compound  /  Molar mass of empirical formula Ratio = 98.96 g/mol / 47.46 g/mol  2.08Since the ratio is approximately 2, the molecular formula of the compound is C2Cl2.Now, we can find the percent composition of the compound.Percent composition of Carbon  C  =  2 * 12.01 g/mol  /  98.96 g/mol  * 100Percent composition of Carbon  C   24.25 %Percent composition of Chlorine  Cl  =  2 * 35.45 g/mol  /  98.96 g/mol  * 100Percent composition of Chlorine  Cl   75.75 %The percent composition of the compound C2Cl2 is approximately 24.25% Carbon and 75.75% Chlorine.
