A 965 solution is diluted to a volume of 1.10 and a concentration of 8.00 . What was the initial concentration?

You have no units.

To find the initial concentration of the solution, we can use the dilution equation:

C1V1 = C2V2

where:
C1 = initial concentration of the solution
V1 = initial volume of the solution
C2 = final concentration of the solution
V2 = final volume of the solution

In this case, we are given:
C2 = 8.00
V2 = 1.10 mL

Since the solution is diluted, we know that V1 > V2. However, the initial volume of the solution (V1) is not provided in the question. Without this information, we cannot calculate the initial concentration (C1).

Please provide the initial volume of the solution (V1) for us to proceed with the calculations.
