|                        | BaCl₂  | BaCl₂ • H₂O | BaCl₂ • 2 H₂O | BaCl₂ • 3 H₂O |
|------------------------|--------|-------------|---------------|---------------|
| Mass of anhydrous BaCl₂ (amu) | 208.23 | 208.23      | 208.23         | 208.23         |
| Mass of H₂O molecules in Hydrate (amu) | 0.00   | 18.02       | 36.04          | 54.06          |
| Mass of Hydrate (amu)     | 208.23 | 226.25      | 244.27         | 262.29         |
| Percent H₂O in Hydrate (%)| 0.00 % | 7.97 %      | 14.8 %         | 20.6 %         |

Compare the experimental percent water you calculated for the barium chloride hydrate in Question 6 in this assignment with the theoretical percent water values calculated from the possible formulas in the table above. Do you think that the formula for your hydrate is BaCl₂ • H₂O, BaCl₂ • 2 H₂O, or BaCl₂ • 3 H₂O?

Select one:
- a. BaCl₂ • H₂O
- b. BaCl₂ • 2 H₂O
- c. BaCl₂ • 3 H₂O
- d. The data is inconclusive: it could be either BaCl₂ • H₂O OR BaCl₂ • 2 H₂O
- e. The data is inconclusive: it could be either BaCl₂ • 2 H₂O OR BaCl₂ • 3 H₂O
