  eqivalent weight = molecular weight / n-factor


the n-factor of salts is the total no of cations on salt. 


as Na2CO3 is a salt and it has two cations or it has +2 positive charge , it means the n-factor of Na2CO3  is 2 


so , its equivalent weight is  =  106/2 gm 


but acc to question u hav asked for 2 equivalent  , therefore  , mass  = 2 × 106⁄2  = 106 gm
