A solution of monobasic acid with molarity `3xx10^(-2)`M has a freezing point depression of `0.06^(@)C`. Calculate `pK_(a)` of the acid (Molal depression constant of water is `1.86^(@)C//m`)

Explanation

To solve the problem step by step, we will use the provided information about the freezing point depression and the molality of the solution. Here’s the step-by-step solution:

### Step 1: Understand the relationship between freezing point depression and molality
The freezing point depression (\( \Delta T_f \)) is given by the formula:
\[ \Delta T_f = i \cdot K_f \cdot m \]
where:
