Two different (pure) solids from the same compound?
« on: May 18, 2010, 04:03:42 PM »
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!
