Asked by Amanda
mass of crucible- 18.50g
mass of crucible+hydrate- 19.50g
mass of crucible+anhydrous salt 1st heating- 19.10g
mass of crucible+anhydrous salt 2nd heating- 19.10g
Questions: 1. calculate mass of water lost from your sample
2. calculate % of water in sample CuSO4*5H2O
3. calculate % error using actual value calculated in the prelab
4. why is it important to make sure all masses of salt agree after each heating?
