Question 8

In a titration, 25.00 cm325.00\text{ cm}^325.00 cm3 of sulfuric acid (H2SO4\text{H}_2\text{SO}_4H2​SO4​) reacted with 18.40 cm318.40\text{ cm}^318.40 cm3 of 0.150 mol/dm30.150\text{ mol/dm}^30.150 mol/dm3 sodium hydroxide solution (NaOH\text{NaOH}NaOH).

The equation for the reaction is:

H2SO4(aq)+2NaOH(aq)→Na2SO4(aq)+2H2O(l) \text{H}_2\text{SO}_4(\text{aq}) + 2\text{NaOH}(\text{aq}) \rightarrow \text{Na}_2\text{SO}_4(\text{aq}) + 2\text{H}_2\text{O(l)} H2​SO4​(aq)+2NaOH(aq)→Na2​SO4​(aq)+2H2​O(l)

Calculate the concentration of the sulfuric acid in mol/dm3mol/dm^3mol/dm3.
