25 g/eq

Explanation:

"Equivalents of acid = Normality of acid × Volume of acid in litres"Equivalents of acid = Normality of acid × Volume of acid in litres

= 0.2 N × 100 cancel(ml) × 10^-3 l/cancel(ml) = 0.02 color(white)x"equivalents"

For complete neutralisation
Equivalents of acid = Equivalents of base

"Equivalent weight" = "Weight" / "Equivalents" = (0.5 g) / (0.02 color(white)"o""equivalents") = 25 gram/equivalent
