When copper was exposed to air and heated, it was found that the black compound formed has a copper-to-oxygen mass ratio of 4:1. The experiment was repeated several times and gave the same results. Please explain this finding based on Dalton's atomic theory. Thank you so much!

The theory suggests:"All atoms of a given element are identical in mass and properties."
Since Copper has Mr 64 and oxygen's Mr 16..we get 4:1 ratio.
This suggests,according to the theory that all atoms of copper and oxygen have identical masses ....
Note:
(this is wrong today as isotopes exist and the reason they dint interfare in the questions repeating experiments is that they exist in small proportions!)
