The resistance of conductivity cell with cell constant 1 . 14   cm - 1 , containing 0 . 001 M   KCl at 298   K is 1500 Ω . The molar conductivity of 0 . 001 M   KCl solution at 298   K in S   cm 2   mol - 1 is (Integer answer)
Correct answer
760
Step-by-step solution
k = 1 R × ℓ A = 1 1500 × 1 . 14   S   cm - 1 ⇒ ∧ m = 1000 × 1 . 14 1500 0 . 001   S   cm 2   mol - 1 = 760   S   cm 2   mol - 1 ⇒ 760
