1.547 g of anyhydrous sodium carbonate were dissolved in deonised water and the solution was made up to 250cm3?
In a graduated flask.25.0cm3 of this solution neutralized24.6cm3 f dilute sulphuric acid. Calculate the concentration of sodium carbonate and sulphuric acid in moles per dm3

Write an equation. This helps a lot.

You already 'have' the concentration of your sodium carbonate. You have the weight. You can find the number of moles. And since you have the volume, you can get its concentration.

With your equation, work out the number of moles in the sulphuric acid, and with the volume of sulphuric acid, find the last concentration. :)

Hope it helped.
