Calculate `Lambda_(m)^(oo)` for acetic acid, given,
`Lambda_(m)^(oo)(HCl)=426 Omega^(-1)cm^(2)mol^(-1),Lambda_(m)^(oo)(NaCl)=126Omega^(-1)cm^(2)mol^(-1)`,
`Lambda_(m)^(oo)(CHCOONa)=91Omega^(-1)cm^(2)mol^(-1)`

Explanation

To calculate the molar conductance at infinite dilution (\( \Lambda_m^{\infty} \)) for acetic acid (\( \text{CH}_3\text{COOH} \)), we will use Kohlrausch's Law, which states that the molar conductance of an electrolyte at infinite dilution is equal to the sum of the molar conductances of its constituent ions.

### Step-by-Step Solution:

1. **Identify the ions for acetic acid**:
Acetic acid dissociates in water as follows:
\[
\text{CH}_3\text{COOH} \rightarrow \text{H}^+ + \text{CH}_3\text{COO}^-
