Ascientist finds one carbon atom for every two oxygen atoms in a sample of compound x. for which other samples of compound x should this ratio hold true?

The formula or chemical formula of a compound is same irrespective of source / mode of synthesis . Thus if a sample of compound has one carbon atom for every two atoms of oxygen (CO2), the formula will remains the same

So the answer is that for all other samples the compound X should hold this ration true.

all samples

Explanation:

A compound consists of two or more elements that are chemically combined in specific proportions. Every sample of compound X, no matter how large or small, will have one carbon atom for every two oxygen atoms.

h let me think

i think it's c. i'm not sure but i think so.
