JEE Main 17 March 2021, Shift 2, Chemistry Q56

Question 56 of 90 in this shift, Chemistry question 26 of 30, Section B.

A KCl solution of conductivity 0.14 S m−10.14\ \mathrm{S\ m^{-1}} shows a resistance of 4.19 Ω4.19\ \Omega in a conductivity cell. If the same cell is filled with an HCl solution, the resistance drops to 1.03 Ω1.03\ \Omega. The conductivity of the HCl solution is __________×10−2 S m−1\times 10^{-2}\ \mathrm{S\ m^{-1}}. (Round off to the Nearest Integer).
