In solution form oxalic acid dihydrate  decomposes into ions. So it is possible to divide the molecular weight by 2 and express its equivalent weight as a number.

In crystalline form oxalic acid does not dissociate into ions. It exists as (COOH)2 . 2H2O.   Perhaps there are resonating structures in the crystal with ionic nature.  It is not possible to calculate its equivalent weight.
