Answer:
- Molar Conductivity of the solution is 500 S cm² mol⁻¹
Given:
- Molarity (M) = 0.01 M
- Resistance (R) = 200 Ω
- Cell constant = 1 cm⁻¹
Explanation:
We Know from the formula,
⇒ Cell constant = κ × R
Here,
- κ Denotes conductivity.
- R Denotes resistance.
⇒ 1 = κ × 200
⇒ κ = 1/200
⇒ κ = 1/200 S cm⁻¹
∴ Conductivity (κ) of the solution is 1/200 S cm⁻¹.
From the formula we know,
Here,
- κ Denotes conductivity.
- M Denotes Molarity.
Substituting the values,
∴ Molar Conductivity of the solution is 500 S cm² mol⁻¹.
