Strategy:
 Molarity () measures the concentration of a solution as moles of solute per Litre of solution. First, convert the given mass of the solute to moles, and then divide by the total solution volume in Litres.

Step 1: Calculate moles of } \ce{Na2CO3}
Molar mass .

Step 2: Calculate Molarity
Volume .
