The Express your answer using two significant figures. neutralization reaction is: My Answers Give Up Part B 205 mL of 0.140 MH2SOs Express your answer using three significant figures. My Answers Give Up Part C 60 mL of 0.120 M H2SO4 Express your answer using two significant figures.

Explanation / Answer

Neutralization of H2SO4 with KOH

Part A : Volume of KOH required = 2 x moles of H2SO4/molarity of KOH

= 2 x 0.255 M x 30 ml/0.255 M

= 60 ml

Part B : Volume of KOH required = 2 x moles of H2SO4/molarity of KOH

= 2 x 0.140 M x 200 ml/0.255 M

= 219.61 ml

Part C : Volume of KOH required = 2 x moles of H2SO4/molarity of KOH

= 2 x 0.120 M x 60 ml/0.255 M

= 56.5 ml
