Enthalpy of dissociation of `H_(2)O` molecules into `H^(+)` and `OH^(-)` ions is `"…....................." kJ mol^(-1)`

Explanation

To determine the enthalpy of dissociation of water (H₂O) into hydrogen ions (H⁺) and hydroxide ions (OH⁻), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Reaction**:
The dissociation of water can be represented as:
\[
H_2O \rightarrow H^+ + OH^-
