Answer:
0.204 mol
Explanation:
Step 1: Write the balanced equation for the heating of calcium chloride dihydrate
CaCl₂.2H₂O ⇒ CaCl₂ + 2H₂O
Step 2: Calculate the moles of calcium chloride dihydrate
The<em> molar mass of CaCl₂.2H₂O</em> is 147.01 g/mol. The moles corresponding to 15.0 g of CaCl₂.2H₂O are:

Step 3: Establish the molar ratio of CaCl₂.2H₂O to H₂O
According to <em>the balanced equation</em>, the molar ratio of CaCl₂.2H₂O to H₂O is 1:2.
Step 4: Use the molar ratio to calculate the moles of water produced from 0.102 moles of calcium chloride dihydrate

I'm not sure it depends if it has any hydroxide ions which in that case it would be alkaline, but if that's the question I'd say tthat the substance is neutral
