Question

Hydrated copper sulfate is heated. Using the speculative chemical equation CuSO4*5H2O-->CuSo4+5H2O, show how you could have predicted, by calculations, what the final weights in the crucibles might be. Show calculations for two starting weights between 1 and 4 grams.

Answer 1

1 g CuSO4.5H2O x (molar mass CuSO4/CuSO4.5H2O) = ? wt CuSO4.
Starting weight = wt xble + 1g
Ending weight = wt xble + ?wt CuSO4
