If two samples of a pure compound have ratios 20:25 and 4:5 what is the conclusion?

Answer and explanation

Correct answer: They show the same ratio

Dividing both terms of 20:25 by 5 gives 4:5. Thus, the mass ratio of the constituents is the same in both samples, consistent with the law of definite proportions for a pure compound. Option B is incorrect because the ratios are not different. Exam tip: reduce ratios to their simplest form before comparing them.
