A KCl solution of conductivity 0.14 S m^$$-$$1 shows a resistance of 4.19$$\Omega$$ in a conductivity cell. If the same cell is filled with an HCl solution, the resistance drops to 1.03$$\Omega$$. The conductivity of the HCl solution is ____________ $$\times$$ 10^$$-$$2 S m^$$-$$1. (Round off to the Nearest Integer).
