25.3g sodium carbonate, Na2CO3, was dissolved in enough water to make 250mL of solution. If sodium carbonate dissociates completely, molar concentration of Na+ and carbonate ions are respectively: 25.3g sodium carbonate molar concentration of Na+ and carbonate ions are respectively: Na2CO3 was dissolved in enough water to make 250mL of solution.
