Question
I am unsure how to work on these two problems with this data
Transcribed Image Text:determined. Use the following data to perform this calculation for copper (II) sulfate.
Mass of crucible
Mass of crucible + hydrated copper (II) sulfate
25.678 g
30.668 g
Mass of crucible + anhydrous salt after 1st heating 28.987g
Mass of crucible + anhydrous salt after 2nd heating 28.870g
Mass of crucible + anhydrous salt after 3rd heating 28.868g
What is the empirical formula of the hydrated salt?
In the MgO lab procedure you were to go through multiple heatings and choose the
largest stabilized mass, however in the hydrate lab described above you use the lowest
mass achieved. Explain why each mass (highest vs. lowest) was chosen with reference to
the reactions occurring in each lab.
