What is the concentration of nitrate ions in a 3.79M #Mg(NO_3)_2# solution? Chemistry Solutions Molarity 1 Answer anor277 Nov 30, 2015 If the solution has a concentration of #3.79# #mol# #L^-1# in #Mg(NO_3)_2#, then the concentration of the nitrate is twice this value. Explanation: #Mg(NO_3)_2(s) rarr Mg^(2+) + 2NO_3^-# #[Mg^(2+)] = 3.79 mol*L^-1; [NO_3^-] = ??# Answer link Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400...
