A stock solution containing Mn2 ions was prepared by dissolving 1.584g of pure manganese metal in nitric acid and diluting to a final volume of 1.000L. The following solutions were then prepared by dilution:a. For solution A, 50.00mL of stock solution was diluted to 1000.0mL. b. For solution B, 10.00mL of solution A was diluted to 250.0mL. c. For solution C, 10.00mL of solution B was diluted to 500.0mL. Calculate the concentrations of the stock solution and solutions A, B and C.3
