Given :
volume of CH₃COOH = 0.015M
Volume of NaOH = 0.015M
Molar conductivity of CH₃COOH = 6.3×10⁻⁴ S/CM
To find :
Molar conductivity of the mixture
Solution :
- Molarity of CH₃COONa = 0.015V/2V
=0.0075M
- Molar conductivity of mixture = K×1000/M
=6.3×10⁻⁴ ×1000 / 0.0075
=81M
- The Molar conductivity of the mixture is 81M

The molar conductivity of CH3COONa is 81 M
Given:
The volume of CH₃COOH = 0.015 M
The volume of NaOH = 0.015 M
The molar conductivity of CH₃COOH = 6.3×10⁻⁴ S/CM
To find:
Molar conductivity of CH₃COONa = ?
Step-by-step explanation:
CH₃COOH + NaOH → CH₃COONa
Molality of CH₃COONa = 0.015/2
∴ Molality of CH₃COONa = 0.0075 M
The molar conductivity is given by the formula:
λ = (K × 1000)/M
On substituting the values, we get,
λ = (6.3 × 10⁻⁴ × 1000)/0.0075
∴ λ = 81 M
