Calculate _ H O A C ^ using appropriate molar conductances of the electrolytes listed above at infinite dilution in H ₂ O at 25^ C .
Options
- A517.2
- B552.7
- C390.7
- D217.5
Correct answer
C. 390.7
Step-by-step solution
aligned & _ HOAC ^ = _ NaOAC ^ + _ HCl ^ - _ NaCl ^ & =91.0+426.2-126.5 ~S ~cm ^2 ~mol ⁻¹ & =390.7 ~S ~cm ^2 ~mol ⁻¹ aligned
