here is your ➡️Given ➡️550 ohm. Specific conductivity = 0.002768 ohm⁻¹ cm⁻¹_____ Cell constant =specific conductivity × resistance = 0.002768 × 550 = 1.5224 .___Conductance for Znso4 =1/R =1/72.18 = 0.014 _____ Specific conductance = cell constant × resistance = 1.5224 × 0.014 = 0.021 . ________________________ Molar Conductance Λ = κ × 1000 / M. ____ ∵Molarity = Normality × n factor = (1/10) × 2 Molarity = 0.2 M___________ Λ = 0.021 × 1000 / 0.2 = 21/0.2 = 105.
