Hint: Atomic Mass: Copper (Cu )= 64 amu, Sulfur (S) = 32 amu , Oxygen (O) = 16 amu, Hydrogen (H ) = 1 amu
You might get an answer here if you are very lucky but this is not the best forum for a question like this.
There must be heaps of science/chemistry forums about.
I know there is a section in mathhelpforum.com that deals with chemistry and physics questions as well.
