## Chemistry: A Molecular Approach (3rd Edition)

In sample 1, the ratio of Cl to C = $448 : 38.9= 11.516$ In sample 2, the ratio of Cl to C = $134 : 14.8= 9.05$ The law of definite proportions states that all samples of a given compound, regardless of their source or how they were prepared, have the same proportions of their constituent elements. But in the results obtained, different samples of carbon tetrachloride have different proportions of their constituent elements. Hence, the results are not consistent with the law of definite proportions.
