Question
![A chemist prepares a solution of potassium dichromate \((K_2Cr_2O_7)\) by measuring out 63.7 \(\mu\text{mol}\) of potassium dichromate into a 450. mL volumetric flask and filling the flask to the mark with water.
Calculate the concentration in \(\mu\text{mol/L}\) of the chemist's potassium dichromate solution. Be sure your answer has the correct number of significant digits.
**Diagram Explanation:**
There is a box containing the expression for the concentration unit:
\[
\frac{\mu \text{mol}}{\text{L}}
\]
Next to this box, there are options:
1. A refresh icon.
2. A checkmark and cross icon for correct/incorrect input.
3. A question mark, possibly for help or additional information.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F70db747f-c273-46b7-a4bc-ce3db4db6b91%2F4afce593-5819-4f6c-a7d9-767312ffa17b%2F0tyik0t_processed.png&w=3840&q=75)
