What is the final volume of NaOH solution prepared from 250.0mL of 0.800M NaOH if you wanted the final concentration to be 0.200M

c1v1 = c2v2

c = concn
v = volume

250 mL x 0.800M = mL x 0.200M
Solve for mL

1000

To determine the final volume of NaOH solution, we can use the dilution formula:

M1 * V1 = M2 * V2

Where:
M1 = initial concentration of NaOH
V1 = initial volume of NaOH
M2 = final concentration of NaOH
V2 = final volume of NaOH

Let's substitute the given values into the formula:

(0.800 M) * (250.0 mL) = (0.200 M) * V2

Now, we can solve for V2:

(0.800 M * 250.0 mL) / 0.200 M = V2

V2 = 1000 mL

Therefore, the final volume of NaOH solution needed to prepare a 0.200 M solution from 250.0 mL of 0.800 M NaOH is 1000 mL or 1.00 L.

To find the final volume of NaOH solution, we can use the dilution formula:

C1 * V1 = C2 * V2

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, we have:
C1 = 0.800 M (initial concentration)
V1 = 250.0 mL (initial volume)
C2 = 0.200 M (final concentration)
V2 = ?

To find V2, we can rearrange the formula:

V2 = (C1 * V1) / C2

Now let's substitute the given values into the equation:
V2 = (0.800 M * 250.0 mL) / 0.200 M

First, multiply the initial concentration (C1) by the initial volume (V1):
V2 = (0.800 M * 250.0 mL)

Then divide the result by the final concentration (C2):
V2 = (200.0 mL) / 0.200 M

Finally, calculate the result:
V2 = 1000.0 mL

Therefore, the final volume of the NaOH solution will be 1000.0 mL or 1.0 L.
