Two samples of carbon tetrachloride are decomposed into their constituent elements. One sample produces 32.4 g of carbon and 373 g of chlorine, and the other sample produces 12.3 g of carbon and 112 g of chlorine. Are these results consistent with the law of constant composition? Explain your answer.
Moles of C in the first sample = 32.4 / 12 = 2.7
moles of Cl = 373/35.5 = 10.51
ratio C : Cl = 2.7 : 10.51
divide by the smallest
C: Cl = 1:3.9
in the second
moles of C = 12.3/12 = 1.025
moles of Cl = 112/35 = 3.2
ratio C:Cl = 1.025 : 3.2 = 1 :3.12
these results are not consistent with the the law of composition as the molar ratio of the components are different .
