Hi, I've found this question on the internet but can't figure out what the correct answer is.
There's no rush on this question, I just want to know the answer...

The question goes as follows:
"
An analysis for copper was performed on two pure solids. One solid was found to contain 43.0% copper; the other contained 32.0% copper. Could these solids be samples of the same copper-containing compound? Explain your answer.
"

The word "sample" makes me think it couldn't be, since those solids would both have to stem directly from the compound, wouldn't they?

Anyway, thanks in advance!
