The solubility of `Sr(OH)_(2)` at `298 K` is `19.23 g L^(-1)` of solution. Calculate the concentrations cf strontium and hydroxyl ions and the `pH` of the solution.

Explanation

To solve the problem, we need to calculate the concentrations of strontium ions (Sr²⁺) and hydroxyl ions (OH⁻) from the solubility of strontium hydroxide (Sr(OH)₂) and then find the pH of the solution.

### Step 1: Calculate the molar mass of Sr(OH)₂
The molar mass of strontium hydroxide (Sr(OH)₂) can be calculated as follows:
- Molar mass of Sr = 87.62 g/mol
- Molar mass of O = 16.00 g/mol (2 oxygen atoms)
- Molar mass of H = 1.01 g/mol (2 hydrogen atoms)
