What must be the molarity of BaCl ₂ solution to have molar conductivity 240 , ⁻¹ cm ^2 mol ⁻¹ and conductivity 0.012 , ⁻¹ cm ⁻¹ at 25^ C ?

Step-by-step solution

The relationship between molar conductivity _m , conductivity , and molarity M is given by the formula: _m = 1000 M Given values are: _m = 240 , ⁻¹ cm ^2 mol ⁻¹ = 0.012 , ⁻¹ cm ⁻¹ Substituting the given values into the formula: 240 = 0.012 1000 M 240 = 12 M M = 12 240 M = 0.05 , M Answer: 0.05 M
