calculate the molarity of sodium thiosulfate secondary solution using the volume of the sodium thiosulfate I used in lab and the molarity of the potassium iodate primary standard solution. The molarity of the potassium iodate is 0.0104 M, and I used 10 mL of it to standardize the sodium thiosulfate. I did three trials and my volumes for the sodium thiosulfate were 12.5 ml, 11.1 ml, and 10.2 ml. I am not sure how to get the molarity of the sodium thiosulfate secondary solution for each trial from this information.
