The solubility of `CaF_2` in water at 298 K is ` 1.7 xx 10 ^(-3)` grams per ` 100 cm ^(3)` .Calculate the solubility product of `CaF_2` at 298 K.

Explanation

To calculate the solubility product (Ksp) of calcium fluoride (CaF₂) at 298 K, we will follow these steps:

### Step 1: Determine the Molecular Mass of CaF₂
- Calcium (Ca) has an atomic mass of approximately 40 g/mol.
- Fluorine (F) has an atomic mass of approximately 19 g/mol.
- Since there are two fluorine atoms in calcium fluoride, the molecular mass of CaF₂ can be calculated as follows:
