The correct option is A 4.0 N H2SO4
From the relation,
NormalityMolarity=Molecular massEquivalent mass=n
For 2 N HCl,
Molarity=Normality×Equivalent weightMolecular weight
Molarity=2×36.536.5=2
For 4N H2SO4, Molarity=4×4998=2
Hence, 4N H2SO4 and 2N HCl solution will have the same molar concentration.
