3. Using the balanced symbol equation forthe reaction, calculate the number of moles of hydrochloric acid needed to neutralise 25cm cubed of sodium carbonate solition used.
Balanced equation: Na2CO3(aq) + 2HCl(aq) -> 2NaCl(aq) + CO2(g) + H2O(l)
4. Hence determine the concentration of the hydrochloric acid, recording the value to the appropriate number of significant figures

You need to use and rearrange the equation
The generic formula used for this type of question:
Find the molar ratio and find out the number of moles of each substance using the equation rearranged above then look at the molar relationship to find the concentration needed.
