Which option is against multiple proportions?

Answer and explanation

Correct answer: It describes the fixed mass ratio of elements in only one sample of a compound

The law of multiple proportions applies when the same two elements form two or more compounds. For a fixed mass of one element, the masses of the other element combine in simple whole-number ratios; for example, oxygen in CO and CO₂ is in the ratio 1:2 for the same mass of carbon. Option D describes the law of definite proportions, not multiple proportions. Exam tip: the phrase “one compound” usually points to the law of definite proportions.
