Composition of a Copper Sulfate Hydrate Lab
1. The mass of the hydrate used was 0.99 grams.
2. The mass of the water lost is 0.34 grams.
3. The percentage of water in the hydrate is 40%.
4. 11% was our percent error. Possible explanations for this error may have been inaccurate readings of the mass of the Copper Sulfate Hydrate or insufficient time to heat the substance.
5.
a) 0.019 was the number of moles of water of water evaporated.
b) 0.0041 was the number of CuSO4 remaining.
c) 5 was the ratio of moles from CuSO4 to H20.
d) CuSO4 x 5H20 was the empirical formula.
My percent error was high and I believe that the coefficient for water is lower than the actual coefficient.
