In two compounds, a fixed 9 grams of A combines with 12 grams and 30 grams of B. What is the simple ratio of B?

Answer and explanation

Correct answer: 2:5

The governing principle is the law of multiple proportions. Since the same mass of A, 9 g, combines in both compounds, the comparison must be made only between the corresponding masses of B. These are 12 g and 30 g, so the required ratio is 12:30. The greatest common divisor of 12 and 30 is 6. Dividing both terms by 6 gives 12 ÷ 6 : 30 ÷ 6 = 2:5. Therefore, option A is correct. Option B reverses the order of the compounds. Option C is not obtained by valid simplification, because 12:30 is equal to 2:5, not 3:5. Option D is also not equivalent to the given ratio. The fixed mass of A is what permits this comparison under the stated law.
