### Analytical Data Table

#### Table 1: Complete this table

| Known          | Distance Travelled (cm) | Rf Value |
|----------------|-------------------------|----------|
| Solvent        | 5.2                     |          |
| Aspirin        | 3.0                     |          |
| Acetaminophen  | 1.8                     |          |
| Caffeine       | 0.40                    |          |
| Ibuprofen      | 3.5                     |          |

To be completed:

1. **Calculate Rf Value for all Above Compounds:**
   The Rf (Retention Factor) value is calculated using the following formula:
   \[
   Rf = \frac{\text{Distance travelled by the compound}}{\text{Distance travelled by the solvent}}
   \]

2. **Formula and Calculations:**
   - For Aspirin:
     \[
     Rf_{\text{Aspirin}} = \frac{3.0}{5.2} \approx 0.577
     \]
   - For Acetaminophen:
     \[
     Rf_{\text{Acetaminophen}} = \frac{1.8}{5.2} \approx 0.346
     \]
   - For Caffeine:
     \[
     Rf_{\text{Caffeine}} = \frac{0.4}{5.2} \approx 0.077
     \]
   - For Ibuprofen:
     \[
