Question
At 298 K, the limiting molar conductivity of a weak monobasic acid is 4×102S cm2 mol−1. At 298 K, for an aqueous solution of the acid the degree of dissociation is α and the molar conductivity is y×102S cm2 mol−1 . At 298 K, upon 20 times dilution with water, the molar conductivity of the solution becomes 3y×102S cm2 mol−1.
The value of α is .
