Any help with this would be greatly appreciated, I couldn't get any straight answers from google.
That's not surprising, google can't solve everything. Pretty much the only way that would work, would be if the teacher got the problem from Google, and you fund it again. You wouldn't learn anything that way.
Anyway ...
are the compounds the same? if not, what is the lowest whole number ratio of copper that combines with a given mass of chlorine
Do you know what a ratio is? Ratios of masses are the same as for ratios of numbers, even if ratios of chemical masses in a computed have a special meaning.
Compound A has a mass of copper and a mass of chlorine, Compound B has
less copper and
more chlorine. Can they possibly have the same ratio?
