Question 44

In a titration, 20.00 cm3 of dilute sulfuric acid reacted with 22.50 cm3 of 0.150 mol dm-3 potassium hydroxide solution, KOH\text{KOH}KOH.

H2SO4+2KOH→K2SO4+2H2O \text{H}_2\text{SO}_4 + 2\text{KOH} \rightarrow \text{K}_2\text{SO}_4 + 2\text{H}_2\text{O} H2​SO4​+2KOH→K2​SO4​+2H2​O

Calculate the concentration of the dilute sulfuric acid, H2SO4\text{H}_2\text{SO}_4H2​SO4​, in mol dm−3\text{mol dm}^{-3}mol dm−3. Give your answer to 3 significant figures.
