# Problem: A stock solution containing Mn 2+ ions was prepared by dissolving 1.584 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 A, 50.00 mL of stock solution was diluted to 1000.0 mL.For solution B, 10.00 mL of solution A was diluted to 250.0 mL.For solution C, 10.00 mL of solution B was diluted to 500.0 mL.Calculate the concentrations of the stock solution and solutions A, B, and C.

###### FREE Expert Solution

We are being asked to calculate the concentrations of the stock solution and solutions A, B, and C.

When dealing with dilution we will use the following equation:

M1 = initial concentration
V
1 = initial volume
M
2 = final concentration
V
2 = final volume

We are going to do the following steps:

Step 1: Determine the concentration of the stock solution

Step 2: Determine the concentration of solution A

Step 3: Determine the concentration of solution B

Step 4: Determine the concentration of solution C

To calculate the concentration of the dilute solutions,
