What is the concentration of k + ions in a 0.025 m k2co3 solution assuming complete dissociation?

The answer to this question would be: 0.050 m

In this question, you have a 0.025m concentration of K2CO3 or potassium carbonate solution. The compound will dissociate into 2 K + and 1 (CO3) 2-

Then the amount of K + ion in this solution assuming complete dissociation should be: 2/1 * 0.025m = 0.050m
