Nicotinic acid `(K_(a) = 1.4 xx 10^(-5))` is represented by the formula `HNiC`. Calculate its percent dissociation in a solution which contains `0.10` moles of nicotinic acid per `2.0L` of solution.

Explanation

To calculate the percent dissociation of nicotinic acid (HNiC) in a solution, we will follow these steps:

### Step 1: Calculate the Molarity of the Solution
We are given that there are 0.10 moles of nicotinic acid in 2.0 L of solution. The molarity (C) can be calculated using the formula:

\[ C = \frac{\text{moles of solute}}{\text{volume of solution in liters}} \]
