Someone investigating the properties of solutions containing carbonate ions prepared a solution containing 5.639g Na2CO3 in a flask of volume 250ml. Some of the solution was transferred to a buret. What volume of solution should be dispensed from the buret to provide 8.361 mmol Na2CO3? What volume should be dispensed to provide 6.282 mmol CO3 2-?

Thanks for your help.
