Answer: option B and option C
Explanation:
Answer:
46. 2 moles of NaOH
Explanation:
Balanced chemical equation between sodium hydroxide and sulfuric acid
2NaOH + H2SO4 = Na2SO4 + 2H2O
I mole of sulphuric acid is neutralized by = 2 moles of NaOH
23.1 mole of sulphuric acid is neutralized by = 2 x 23.1
= 46. 2 moles of NaOH
