Question 10
H

A student titrated 20.0 cm3 of sulfuric acid with a solution of potassium hydroxide.

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

24.0 cm3 of 0.500 mol/dm3 potassium hydroxide solution was needed to neutralise the sulfuric acid completely.

a.

Calculate the amount, in mol\text{mol}mol, of potassium hydroxide the student used.
