From the following data, calculate the molar conductivity of KBr in aqueous solution: Conductivity of 2.5 × 10-4 mol dm3 KBr = 3.72 × 10-3 S m-1 , Conductivity of the water=0.6 × 10-3 S m-1 

To calculate the molar conductivity of KBr in aqueous solution, we need to use the equation:

Molar conductivity (Λm) = Conductivity (κ) / Concentration (C)

Given data: Conductivity of 2.5 × 10^-4 mol dm^3 KBr solution (κ_KBr) = 3.72 × 10^-3 S m^-1 Conductivity of water (κ_water) = 0.6 × 10^-3 S m^-1

First, we need to calculate the conductivity of the KBr solution without the contribution of water. This can be done by subtracting the conductivity of water from the conductivity of the KBr solution:
