At 300 K, the degree of dissociation of 0.066 M solution of an acid HA is 0.0145. What would be its degree of dissociation of 0.02 M solution of the acid at the same temperature?

Explanation

To solve the problem step by step, we will use the concept of degree of dissociation (α) and the dissociation constant (Ka) of the acid.

### Step 1: Understand the given data
We are given:
- The concentration of the first solution (C1) = 0.066 M
- The degree of dissociation of the first solution (α1) = 0.0145
- The concentration of the second solution (C2) = 0.02 M
- The temperature is constant (300 K), which means Ka remains the same.
