A 0.357 g of sample of an unknown oxidant is added to an excess solution of KI resulting in the production of I2 (assume a 1:1 ratio for oxidant:I2). The resulting solution was then titrated with a 0.103 M solution of Na2S2O3. The endpoint was reached after adding 16.82 ml of the titrant. Determine the Formula weight of the oxidant to nearest whole number.
