The resistivity of a solution is 25.0 ·cm. Find its conductivity in (S cm ⁻¹ ).

Options

  1. A0.04 S cm ⁻¹
  2. B0.07 S cm ⁻¹
  3. C0.14 S cm ⁻¹
  4. D0.317 S cm ⁻¹

Correct answer

A. 0.04 S cm ⁻¹

Step-by-step solution

Conductivity is the reciprocal of resistivity . = 1 Given = 25.0 cm . = 1 25.0 = 0.04 S cm ⁻¹ Answer: 0.04 S cm ⁻¹
