Data Table
Mass of empty crucible
23.578
grams
Mass of crucible + mass of hydrate
27.432
grams
Mass of crucible + unknown after final heating
25.763
grams
Transfer the information in the Data Table to the Report Table.
Before
you start this virtual experiment, answer the Pre-lab Questions in the space provided on
page 2. To determine the ratio of water to the anhydrous salt, for the unknown hydrate of ZnSO4,
use the above data to complete the Data Sheet on page 3, and show the complete calculation in
the Calculation Sheet on page 4. Finally, write the formula and name of the unknown hydrate on
the Data Table on lines m and n.
