What is the solubility of calcium iodide (in g per 100 cc of cold water)?

This site gives the solubility at three different temperatures. Take your pick.

To determine the solubility of calcium iodide in grams per 100 cc (cubic centimeters) of cold water, we can refer to available solubility data or calculate it based on its molar solubility and molar mass.

Option 1: Referring to available solubility data
The solubility of calcium iodide can be found in solubility tables or reference books. According to solubility data, calcium iodide has a solubility of approximately 121.2 grams per 100 cc of water at 0 °C.

Option 2: Calculation based on molar solubility and molar mass
If you have the molar solubility and molar mass of calcium iodide, you can calculate its solubility in grams per 100 cc.

1. Find the molar solubility of calcium iodide:
The molar solubility represents the number of moles of the solute (calcium iodide) that dissolve in a given volume of solvent (water). Let's assume that the molar solubility of calcium iodide is x mol/L.

2. Calculate the molarity (M) of calcium iodide:
The molarity is the number of moles of solute divided by the volume of the solution in liters. Since we want to find the solubility in grams per 100 cc, we need to convert 100 cc to liters (1 cc = 1 mL, and 1 L = 1000 cc).

Molarity (M) = moles of solute / volume of solution (in liters)

3. Convert molarity to grams per 100 cc:
Using the molar mass of calcium iodide (CaI₂ = 293.89 g/mol), we can convert the molarity to grams per 100 cc.

Grams per 100 cc = (Molarity × Molar mass × 100 cc) / 1 L

By substituting the values, you can calculate the solubility of calcium iodide in grams per 100 cc.

Please note that the calculated value may vary slightly from the experimental values due to factors like temperature and impurities.
