Perhaps I am missing something, but for the composition it should be enough to compare initial state ((NH4)2Ce(NO3)m) with the final one (CeO2), path nor intermediates don't matter.

ae86:
You don't have to take note of the intermediates to calculate the number of molecule of nitrate.
Well if we add to  ((NH4)2Ce(NO3)m) 3 molecules of H20, we have approximately the mass loss at the end of the decomposition. I don't know if this salt could be under the crystallized form.

Borek:
Crystal water can be always a factor, no doubt about it. Thing is, in the case of hydrates such water is typically clearly stated in the formula.

Loosing this water should be visible as a step on the curve. Does the water mass fit the first mass loss step?
