Calculate the total ionic concentration of a weak acid and a weak base (knowing their conductivities) by setting up a proportion with the total ionic concentration and conductivity of a strong acid and a strong base. Basically, we ran out of time and I have no way of finding the CONDUCTIVITIES of .0001 and .0005 molar solutions of both NH3 and HAc, and those four values are all I need in order to complete the experiment. Do you know where I could find those conductivities??
