volumetric analysis question. Help please
hi ppl. i need help on a chem question:
5.00mL of conc. H2SO4 was pipetted into a volumetric flask containing water and the volume made up to exactly 1.00L. Three 20.00mL samples of 0.200molL^-1 NaOH required 22.30, 22.16, 22.17 and 22.18 mL of the acid for neutralisation using phenolphthalein indicator.
Determine the concentration of the conc. sulfuric acid solution.
thx
