Conductivity = Conductance * Cell constant
Conductivity = (1/ resistance )
Cell constant = Conductivity * Resistance
Cell constant = 0.0210 * 60 = 1.26Cm? ¹

Λ? = K * 1000 / M = (2 * 10? * 10³) / 10? ³ = 20 Scm²mole? ¹
For weak acid (α) = Λ? / Λ? = 20 / 190 = 2/19
K? = Cα² / (1 - α) = 10? ³ * (2/19)² / (1 - 2/19)
= 10? ³ * (4/361) / (17/19) = 0.01238 * 10? ³
= 12.38 * 10?
So, ans is 12 (the nearest integer).
