Totally depends on the reaction.
For reduction/oxidation reactions:
n-factor is defined as the number of moles of electrons accepted/gained per mole of the substance.
E.g. 2CO2 + 2 electrons → C2O4(-2)
Here n-factor is 1. So equivalent weight will be 44/1 = 44g/mole.
For acid/base reactions:
n-factor is defined as the number of H+/OH(-1) ions does a compound react with, in a non-redox reaction.
E.g. CO2 + 2OH(-1) → CO3(-2) + H2O
One CO2 molecule is reacting with 2 hydroxyl ions. Thus n-factor is 2 and its equivalent weight is 44/2 = 22g/mole.
