Calculate molar conductivity at infinite dilution for NaBr if molar conductivity at infinite dilution for NaCl , KBr and KCl are 126, 152 and 150 ⁻¹ ~cm ^2 ~mol ⁻¹ respectively
Options
- A128 ⁻¹ ~cm ^2 ~mol ⁻¹
- B302 ⁻¹ ~cm ^2 ~mol ⁻¹
- C278 ⁻¹ ~cm ^2 ~mol ⁻¹
- D176 ⁻¹ ~cm ^2 ~mol ⁻¹
Correct answer
A. 128 ⁻¹ ~cm ^2 ~mol ⁻¹
Step-by-step solution
aligned & ^0 NaBr = ^0 NaCl + ^ KBr - ^ KCl & =126+152-150 & =128 ⁻¹ ~cm ^2 ~mole ⁻¹ aligned
