The value of the limiting molar conductivity ( ^ ) for NaCl , HCl and NaOAc are 126.4, 425.9 and 91.0 ~S ~cm ² mol ⁻¹ , respectively. For HOAc, ^ in S cm ² ~mol ⁻¹ is

Options

  1. A390.5
  2. B299.5
  3. C208.5
  4. D217.4

Correct answer

A. 390.5

Step-by-step solution

aligned ( HOAc ) &= ^ ( NaOAc )+ ^ ( HCl )- ^ ( NaCl ) &=91+425.9-126.4=390.5 aligned
