$\mathrm{Mg}\left(\mathrm{NO}_{3}\right)_{2} \cdot \mathrm{XH}_{2} \mathrm{O}$ and $\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2} \cdot \mathrm{YH}_{2} \mathrm{O}$, represent formula of the crystalline forms of nitrate salts. Sum of $\mathrm{X}$ and $\mathrm{Y}$ is _____________.
Answer (integer)
6
Solution
<p>Magnesium nitrate typically crystallizes as a hexahydrate, which means it has six water molecules in its crystal structure. So, X = 6.</p>
<p>On the other hand, barium nitrate commonly crystallizes as an anhydrous salt, meaning it does not incorporate water molecules into its crystal structure. So, Y = 0.</p>
<p>Therefore, the sum of X and Y would indeed be 6 + 0 = 6.</p>
