If I know that the concentration of Co(NO3)2 is 5.640 M, how do I find the cation molarity and the anion molarity?
The reaction of dissociation will be
Co(NO3)2 = Co2+ + 2NO3-
The molarity of Co2+ is equal to 5.640 M and the molarity of NO3- is 5.640*2 moles = 11.280 M because we have 2 moles of NO3- anion in the solution.
