![### Dilution Calculation Exercise
#### Question
What is the final volume when 25 mL of 0.60 M KMnO₄ is diluted to 0.30 M?
#### Solution
Final Volume = [ ? ] mL of 0.30 M KMnO₄
#### Input Section
There is a text box labeled "Volume KMnO₄ (mL)" where users can input their calculated volume value, followed by an "Enter" button to submit the answer.
##### Explanation for Students
To solve the question, you can use the dilution formula:
\[ C_1V_1 = C_2V_2 \]
Where:
- \( C_1 \) = Initial concentration (0.60 M)
- \( V_1 \) = Initial volume (25 mL)
- \( C_2 \) = Final concentration (0.30 M)
- \( V_2 \) = Final volume
You need to calculate the final volume \( V_2 \):
\[ V_2 = \frac{C_1V_1}{C_2} \]
Substitute the given values into the formula:
\[ V_2 = \frac{0.60 \, \text{M} \times 25 \, \text{mL}}{0.30 \, \text{M}} \]
This allows you to find the final volume after dilution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0e0dd2c8-2c2b-4452-a4b7-24696070e6a2%2F8ac17d97-c6a2-4a71-aabc-61052f8f1083%2F26pf7de_processed.jpeg&w=3840&q=75)
