Two samples have ratios 12:18 and 2:3. Do they agree with definite proportions?

Answer and explanation

Correct answer: Yes, because 12:18 simplifies to 2:3

Yes. Dividing both terms of 12:18 by 6 gives 2:3. Thus, the mass ratio of the components is the same in both samples, which agrees with the law of definite proportions. Different total amounts do not violate the law; the simplest ratio must remain the same. Exam tip: reduce ratios to their simplest form before comparing them.
