Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C and the conductivity of 0.100 mol dm^?3 KCl(aq) is 1.1639 S m^?1. A cell had a resistance of 33.21 ? when filled with 0.100 mol dm^?3 KCl(aq) and 300.0 ? when filled with 0.100 mol dm^?3 CH3COOH(aq). What is the molar conductivity of acetic acid at that concentration and temperature?
