A 2 mL sample was taken of a solution of barium iodate at 10 degree C. the sample was mixed with 2 mL of 0.5 M KI and 2 mL of 1M HCl. The transmittance of the mixture was read and compared to a calibration curve which indicated a concentration of I3^- as 5.52*10^-4 M. Calculate the following: c.) The concentration in moles/L of IO3^- in the original sample.
