Answer:
4.5 M Na+
Explanation:
Multiply the molarity by the volume of the solution to get moles.
Note that there are TWO sodium ions in sodium carbonate, therefore the first-mole calculation must be multiplied by two.
Since molarity is defined as moles of ions/liters of solution, the final molarity will be the sum of the calculated moles divided by the sum of the liters of solution.
