so you have .75M of Na2CO3, and in this chemical there are two Na, so when the chemical dissociates there will be twice the concentration. Therefore its .75M x 2 = 1.5M . should be right.

The sodium carbonate will ionize to generate 2 moles of Na+ ions for every mole of reactant. If you have 0.75 moles of carbonate, you should get 1.5 moles of sodium ions.
