How is the molar conductivity of an elecrolytic solution calculated?

Options

  1. Amolar concentration / electrolytic conductivity
  2. Belectrolytic conductivity x 1000 / molar concentration
  3. Celectrolytic conductivity multiplied by molar concentration
  4. Dmolar concentration / square of electrolytic conductivity x 1000

Correct answer

B. electrolytic conductivity x 1000 / molar concentration

Step-by-step solution

Molar conductivity ( _m ) is defined as the conducting power of all the ions produced by dissolving one mole of an electrolyte in a solution. Mathematically, it is expressed as: _m = 1000 C where is the electrolytic conductivity (specific conductance) in S , cm⁻¹ and C is the molar concentration of the solution in mol , L⁻¹ . Thus, molar conductivity is calculated as electrolytic conductivity 1000 / molar concentration. Answer: electrolytic conductivity x 1000 / molar concentration
