For the strong electrolytes N a O H , N a C l and B a C l 2 the molar ionic conductivities at infinite dilution are 250, 125 and 300 m h o c m 2 m o l – 1 respectively. The molar conductivity of B a O H 2 at infinite dilution ( m h o c m 2 m o l – 1 ) is.

Correct answer

50

Step-by-step solution

λ ο B a O H 2 = λ ο B a C l 2 + 2 λ ο N a O H - 2 λ ο N a C l λ ο B a O H 2 = 300 + 2 250 - 2 125 λ ο B a O H 2 = 300 + 500 - 250 λ ο B a O H 2 = 550 m h o c m 2 m o l – 1
