The molar conductivity of 0.02 M electrolytic solution is 220 ⁻¹ cm ^2 mol ⁻¹ at 25 ^ C . Find its conductivity.

Options

  1. A0.0044 ⁻¹ cm ⁻¹
  2. B0.0022 ⁻¹ cm ⁻¹
  3. C0.0011 ⁻¹ cm ⁻¹
  4. D0.0033 ⁻¹ cm ⁻¹

Correct answer

A. 0.0044 ⁻¹ cm ⁻¹

Step-by-step solution

Given: Molar conductivity, _m = 220 ⁻¹ cm ^2 mol ⁻¹ Concentration, C = 0.02 M The relation between molar conductivity and conductivity is given by: _m = 1000 C Rearranging the formula to solve for conductivity : = _m C 1000 Substituting the given values: = 220 0.02 1000 = 4.4 1000 = 0.0044 ⁻¹ cm ⁻¹ Answer: 0.0044 ⁻¹ cm ⁻¹
