Two samples of a compound have ratios 2:7 and 4:14. Which conclusion is correct?

Answer and explanation

Correct answer: They conform to the law of definite proportions

Dividing both terms of the second ratio, 4:14, by 2 gives 2:7. Thus, the mass ratio of the elements is the same in both samples, in accordance with the law of definite proportions. Option C is incorrect because 4:14 is not a new ratio; it is a multiple form of the same ratio. Exam tip: reduce ratios to their simplest form before comparing them.
