Does knowing the ratio of masses of the elements in a compound lead to the unique chemical identity of the compound? O A. No, because more than one compound can have the same ratio of masses of elements, if the atoms are arranged differently. OB. No, because a compound can have different ratios of masses of its elements, depending on its source. C. Yes, because a molecule of any compound is composed of a whole-number ratio of atoms of its elements, per the law of definite proportions. D. Yes, because each compound has a unique ratio of masses of its elements.

The answer is incorrect  can you solve again?

Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement.   Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…
