"Mass can neither be created nor destroyed" is the statement of

A Gay Lussac Law of gaseous volume
B Law of definite proportion
C Law of conservation of mass
D Law of multiple proportions

Verified Solution

Answer & Solution

Correct Answer

(C) Law of conservation of mass

Step-by-step Solution

Detailed explanation

Law of conservation of mass: -
Mass can neither be created nor destroyed.
Law of multiple proportions
According to this law, if two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole numbers.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
