The limiting molar conductivities of NaI , NaNO 3 and AgNO 3 are 12 . 7 , 12 . 0 and 13 . 3   mSm 2   mol - 1 , respectively (all at 25   ° C ). The limiting molar conductivity of AgI at this temperature is____ mSm 2   mol - 1 .

Correct answer

0

Step-by-step solution

(1) λ m ∞ NaI = 12 . 7 mSm 2   mol - 1 (2) λ m ∞ NaNO 3 = 12 . 0 mSm 2   mol - 1 (3) λ m ∞ AgNO 3 = 13 . 3 mSm 2   mol - 1 λ m ∞ AgI = 1 + 3 - 2 = 12 . 7 + 13 . 3 - 12 . 0 = 26 . 0 - 12 . 0 λ m ∞ AgI = 14 . 0
