The conductivity of a solution containing 2.08 ~g of anhydrous barium chloride in 200 ~mL solution is 6 10⁻³ ohm ⁻¹ ~cm ⁻¹ . The molar conductivity of the solution (in . ohm ⁻¹ ~cm ^2 ~mol ⁻¹ ) is x 10^2 . The value of x is (Atomic mass of Ba =137, Cl =35.5 )
Options
- A1.2
- B2.4
- C3.6
- D3.0
Correct answer
A. 1.2
Step-by-step solution
Conductivity (k) =6 10⁻³ ⁻¹ ~cm ⁻¹ V =200 ~mL =0.2 ~L mass =2.08 ~g aligned & C = n V = ( mass molar mass ) V = ( 2.08 208 ) 0.2 & =0.05 M . aligned aligned & _ m = K 1000 c = (6 10⁻³ )(1000) 0.05 & =120=1.20 10^2 aligned Thus, x =1.2
