Question

Does knowing the ratio of masses of the elements in a compound lead to the unique chemical identity of the compound?

Answer 1

Isomers are compounds that have the same molecular formula but different arranged differently of the atoms.

For example

So even if they have the same proportion of their atoms, the chemical identity is different

The answer is option B: no because more than one compound can have the same ratio of masses of elements if the atoms are arranged differently.
