Specific conductance of `10^(-4)M n`-Butyric acid aqueous solution is `1.9 xx 10^(-9)S m^(-1)`. If molar conductance of n-Butyric acid at infinite dilution is `380 xx 10^(-4) S m^(2) mol^(-1)`, then `K_(a)` for n-Butyric acid is:

Explanation

To find the dissociation constant \( K_a \) for n-Butyric acid, we will follow these steps:

### Step 1: Write down the given data
- Specific conductance (\( K \)) = \( 1.9 \times 10^{-9} \, \text{S m}^{-1} \)
- Concentration (\( C \)) = \( 10^{-4} \, \text{M} \)
- Molar conductance at infinite dilution (\( \Lambda_0 \)) = \( 380 \times 10^{-4} \, \text{S m}^2 \text{mol}^{-1} \)

### Step 2: Calculate the molar conductance at the given concentration
