3moles of sodium hydroxide will neutralize 1mole of citric acid,what volume of 2moles of sodium hydroxide solution will neutralize 50cm of citric acid solution?
I don't think you have all of the information needed to solve the problem. You need molarity of the citric acid and molarity of the NaOH. For whatever it's worth, 50 cm of citric acid is not a volume.
