Options
- A8.74 ⁻¹ , cm ^2 mol ⁻¹
- B21.85 ⁻¹ , cm ^2 mol ⁻¹
- C43.70 ⁻¹ , cm ^2 mol ⁻¹
- D13.65 ⁻¹ , cm ^2 mol ⁻¹
Correct answer
B. 21.85 ⁻¹ , cm ^2 mol ⁻¹
Step-by-step solution
Given: Conductivity, = 4.37 10⁻⁴ , ⁻¹ , cm ⁻¹ Molarity, M = 0.02 , M The formula for molar conductivity is: _m = 1000 M Substituting the given values: _m = 4.37 10⁻⁴ 1000 0.02 _m = 0.437 0.02 _m = 21.85 , ⁻¹ , cm ^2 , mol ⁻¹ Answer: 21.85 ⁻¹ , cm ^2 mol ⁻¹
