Correct Answer: 6
Solution and Explanation
- The given formulas represent hydrated magnesium nitrate and hydrated barium nitrate.
- The formulas are as follows:
- Magnesium nitrate hexahydrate: \( \text{Mg(NO}_3)_2 \cdot 6\text{H}_2\text{O} \)
- Barium nitrate (anhydrous): \( \text{Ba(NO}_3)_2 \)
- Here:
- \( X = 6 \) (number of water molecules in magnesium nitrate hexahydrate).
- \( Y = 0 \) (number of water molecules in anhydrous barium nitrate).
Calculation:
The sum of \( X \) and \( Y \) is:
\[ X + Y = 6 + 0 = 6 \]
Final Answer:
The sum of \( X \) and \( Y \) is 6.
