![# Chromatography Data Analysis
The table below contains data for a liquid chromatography separation of four compounds, A, B, C, and D, on a 25.0 cm column.
| Compound | Retention Time (min) | Width at the Base (min) |
|----------|----------------------|-------------------------|
| A | 5.14 | 0.448 |
| B | 13.0 | 1.08 |
| C | 14.0 | 1.15 |
| D | 23.6 | 1.89 |
**Calculate the number of theoretical plates, \( N \), for each peak.**
\[ N_A = \]
\[ N_B = \]
\[ N_C = \]
\[ N_D = \]
**What is the average number of theoretical plates, \( N_{avg} \), for the column?**
\[ N_{avg} = \]
These calculations help evaluate column efficiency in chromatography, essential for understanding separation quality.](https://content.bartleby.com/qna-images/question/83ec917b-3e82-4dc1-b5e7-24fa4bff0896/b51abc2a-9cf7-485a-8593-37bf74c09556/z2fq9pl_processed.jpeg)
