A stock solution containing Mn²+ ions was prepared by dissolving 1.861 g pure manganese metal in nitric acid and diluting to a final volume of 1.000 L. The following solutions were then prepared by dilution: For solution 4, 40.00 mL of stock solution was diluted to 1000.0 mL. For solution B, 20.00 mL of solution A was diluted to 250.0 mL. For solution C, 10.00 mL of solution B was diluted to 550.0 mL. Calculate the concentration of the stock solution.
