To solve this problem, we can use the dilution formula:
C1V1 = C2V2
Where:
C1 = Initial concentration
V1 = Initial volume
C2 = Final concentration
V2 = Final volume
Given information:
- Initial concentration (C1) = 0.033 M
- Final concentration (C2) = 0.025 M
- Final volume (V2) = 25 mL
We need to find the initial volume (V1).
Substituting the given values into the dilution formula:
0.033 M × V1 = 0.025 M × 25 mL
V1 = (0.025 M × 25 mL) / 0.033 M
V1 = 1.9 mL
Therefore, the correct answer is 1.9 mL.
C1V1 = C2V2
Where:
C1 = Initial concentration
V1 = Initial volume
C2 = Final concentration
V2 = Final volume
Given information:
- Initial concentration (C1) = 0.033 M
- Final concentration (C2) = 0.025 M
- Final volume (V2) = 25 mL
We need to find the initial volume (V1).
Substituting the given values into the dilution formula:
0.033 M × V1 = 0.025 M × 25 mL
V1 = (0.025 M × 25 mL) / 0.033 M
V1 = 1.9 mL
Therefore, the correct answer is 1.9 mL.
