Question

The weights of two elements which combines with one another are in the ratio of their:

• A. atomic weight
• B. molecular weight
• C. equivalent weight
• D. none of the above

Answer 1

The correct option is A atomic weight

According to the law of multiple proportions, when two elements combine to form more than one compound, the weight of one element combined with a fixed weight of the other is in a ratio of small whole numbers.

Hence, the weight of two elements that combine is in the ratio of their atomic weight.

So, the correct option is $A$.
