The sulfuric acid solution had a concentration of 0.304 M.
Start with the balanced chemical equation for this neutralization reaction
Notice that you have a
Since molarity is defined as moles of solute per liters of solution, you can use the molarity and volume of the potassium hydroxide solution to determine how many moles of the base were needed to completely react with the acid.
This means that the sulfuric acid solution contained
Since you know the volume of the sulfuric acid and how many moles it contained, you can determine its molarity by
