There are 4 moles of Cu per mole of Paris Green, which means
that the amount of CuO moles obtained from the decomposition will
be 4 times the number of moles of Paris Green that were
decomposed.
The molar mass of Paris Green is 1013.8 g/mol, so the number of
initial moles is:
The number of moles of CuO produced from the decomposition is 4 times this, which is: 3.95x10-3 moles. This number represents a mass of (the molar mass of CuO is 79.55 g/mol):
