Question
![**Problem Statement:**
3.5 mg of optically-enriched (-) sugar P was dissolved in 1.00 mL methanol in a 1.00 mL volumetric flask. The optical rotation was found to be -0.0222° in a 5.0 cm cell. What is the specific rotation? Write out all your work and upload it here.
**Diagram/Explanation Section:**
- **No diagrams or graphs** are present in this image. The problem concerns the calculation of specific rotation using provided data.
**Conceptual Background:**
The specific rotation (\([\alpha]\)) is calculated using the formula:
\[
[\alpha] = \frac{\alpha}{l \cdot c}
\]
Where:
- \(\alpha\) = observed optical rotation
- \(l\) = path length of the cell in decimeters
- \(c\) = concentration of the solution in g/mL
**Note for Users:**
Ensure that all units are correctly converted and calculations are thoroughly checked for accuracy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F01604a07-1abb-47f3-85be-4093016fdea3%2F1030e02c-24e8-4b3f-95bc-78140617340f%2Fv4udfb2_processed.jpeg&w=3840&q=75)
