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.
A solution is prepared by mixing 4 ml of .20 M NH3, 1 ml of .20 M HCl, and 5 ml of water. Calculate the concentration of NH3 and NH4+ in the final diluted solution.
