Question

One of the statements of Dalton’s atomic theory is given below: “Compounds are formed when atoms of different elements combine in a fixed ratio.” Which of the following laws is not related to this statement?

• A. Law of conservation of mass
• B. Law of definite proportions
• C. Law of multiple proportions
• D. None of these

Answer 1

The correct option is A Law of conservation of mass

The given Dalton’s atomic postulate is as follows:
“Compounds are formed when atoms of different elements combine in a fixed ratio.” This statement is related to the law of multiple proportions and the law of definite proportions.
Here, Avogadro’s law is related to the number of molecules of the different gases whereas the law of conservation of mass states that the total mass during a reaction is conserved.
Thus, Avogadro’s law and the law of conservation of mass are not related to the given statement of Dalton’s atomic theory.
