The neutralization reaction between potassium hydroxide and sulfuric acid is as follows

2KOH + H2SO4 - - - > K2SO4 + 2H2O

number of moles of KOH = (43.74 x 0.500) / 1000 = 0.02187 moles

the reacting ratio of KOH to H2SO4 is 2:1 therefore the moles of H2SO4 is = 0.021187/2 = 0.01094 moles

concentration (molarity) = (0.01094/50) x 1000 = 0.2188M
