## Question

250mL of a sodium carbonate solution contains 2.65 grams of Na_{2}CO_{3}. If 10mL of this solution is diluted to one litre, what is the concentration of the resultant solution?

(mol. wt. of Na_{2}CO_{3}= 106)

### Solution

0.001 M

Molarity of given Na_{2}CO_{3} sol.

or M_{2} = 0.001 M
