An aqueous solution of glucose containing `12 g` in `100 g` of water was found to boil at `100.34^(@)C`.
Calculate of `K_(b)` for water in `K mol^(-1)Kg`.

Explanation

To calculate the ebullioscopic constant \( K_b \) for water, we will follow these steps:

### Step 1: Determine the change in boiling point (\( \Delta T_b \))
The boiling point of the solution is given as \( 100.34^\circ C \). The boiling point of pure water is \( 100^\circ C \).

\[ \Delta T_b = T_{\text{solution}} - T_{\text{pure water}} = 100.34^\circ C - 100^\circ C = 0.34^\circ C \]
