Molar conductivity is defined as the conductivity of a solution divided the molar concentration of charge-carrying species (ions). Its units are siemens per meter per molarity, or siemens meter-squared per mole. A common symbol is a capital lambda (Λ).

Kohlrausch established that to a high accuracy in dilute solutions, molar conductivity is composed of individual contributions of ions. This is known as the law of independent migration of ions.[1] When v is the number of ions, and λ is the molar conductivity of a specific ion, then for all ions, Kohlrausch's law states that

Λ = Σvi λi
For strong electrolytes, such as salts and strong acids and bases, molar conductivity varies little with concentration, but for weak electrolytes, such as weak acids, molar conductivity depends strongly on concentration, being exponentially smaller with smaller concentration.

Then, to answer your question, we need to know more about the solution (concentration) of BaSO4.
