Iodine number is the grams of iodine atoms (atomic mass $$= 127$$ $$\text{g mol}^{-1}$$) that can react completely with 100 g of a vegetable oil. Iodine monochloride (ICl) is a reagent used to determine iodine number. In an experiment, 25.00 $$\text{cm}^3$$ of 0.100 $$\text{mol dm}^{-3}$$ ICl was added to 127 g of the oil. The unreacted ICl was found to be equivalent to 40.00 $$\text{cm}^3$$ of 0.10 $$\text{mol dm}^{-3}$$ of $$Na_2S_2O_3$$. The iodine number of the oil can be deduced as
