To solve this problem, we can use the formula for dilution: M1V1 = M2V2, where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.

Given in the problem, we have:

M2 = 0.2 M (final concentration)
V1 = 8000 mL (initial volume)
V2 = V1 + 990 mL = 8000 mL + 990 mL = 8990 mL (final volume)

We need to find M1 (initial concentration). We can rearrange the formula to solve for M1:

M1 = M2V2 / V1

Substituting the given values:

M1 = (0.2 M * 8990 mL) / 8000 mL

M1 = 0.224875 M

So, the original concentration of the solution was approximately 0.225 M.
