Question

What is the final ferrous sulfate concentration of a solution prepared by adding 13.4 ml of a 25.0 mm stock solution to 29.8 ml of water?

Answer 1

To find the final ferrous sulfate concentration of the solution, we can use the formula for dilution: C1V1 = C2V2. In this case, the initial volume is 13.4 mL, the initial concentration is 25.0 mM, the final volume is 29.8 mL, and the final concentration is 11.26 mM.

Step-by-step explanation:

To find the final ferrous sulfate concentration of the solution, we can use the formula for dilution:

C1V1 = C2V2

Where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

In this case, the initial volume is 13.4 mL, the initial concentration is 25.0 mM, the final volume is 29.8 mL, and we need to find the final concentration.

Substituting the known values into the formula:

(25.0 mM)(13.4 mL) = (C2)(29.8 mL)

Solving for C2, the final concentration:

C2 = (25.0 mM)(13.4 mL) / (29.8 mL)

C2 = 11.26 mM

Therefore, the final ferrous sulfate concentration of the solution is 11.26 mM.
