If we know the molecular weight
If we know the molecular weight of a substance we implicitely know the atomic composition of that substance - provided that the molecular weight is known to an accuracy which is sufficient to distinguish between molecules having the same nominal mass.
To explain this, let's have a look at a very simple example: suppose we know that our substance has a molecular weight of 28. A quick calculation (considering only the nominal masses of the most abundant isotopes of carbon, hydrogen, oxygen, and nitrogen - 12, 1, 16, and 14, respectively) shows that there are three substances which all have the same molecular mass of 28: C2H4 (ethene), CO (carbon monoxide) and N2 (nitrogen gas).
