Calculate the mass of H2O produced by the decomposition of 2.21g of CuCO3 x Cu (OH)2. What happend to this water?

Question

This question is incredibly important and I am stuck on it, thank you very much for your help

Answer 1

I might be able to help if I knew more about what you were doing. What follows is my guess of what you are doing.
I would write the equation as follows:
CuCO3.Cu(OH)2 --> 2CuO + CO2 + H2O
Here is a link to show you how to calculate the mass water produced.

Where does the water go? If you are decomposing the compound, the water must have evaporated under the heat required for the decomposition. If I have guessed wrong as to what you are doing, please repost (a new post at the top of the first page) and provide more information.
