I need help finding the %Composition for %cychohexane and %toluene. The formula (area of peak/total area) * 100%

### Chromatography Data Summary

This table provides analysis data from a chromatographic experiment, showing details about peaks recorded during the procedure.

| Peak # | Retention Time [min] | Type | Width [min] | Area [pA*s] | Height [pA] | Area [%] |
|--------|----------------------|------|-------------|-------------|-------------|----------|
| 1      | 0.315                | BV S | 0.0204      | 5.06638e4   | 3.84753e4   | 1.98609  |
| 2      | 0.346                | VV S | 0.0184      | 8.56105e4   | 7.75317e4   | 3.35605  |
| 3      | 0.374                | VV S | 0.0263      | 1.30934e4   | 8302.15430  | 0.51328  |
| 4      | 0.494                | VV S | 0.0174      | 2.25497e6   | 1.95844e5   | 88.39802 |
| 5      | 0.558                | VB S | 0.0183      | 1.46591e5   | 1.33145e5   | 5.74655  |

**Totals:**
- **Area [pA*s]:** 2.55093e6
- **Height [pA]:** 2.21590e6

### Explanation

- **Peak #**: Numerical identifier for each peak.
- **Retention Time [min]**: The time at which a compound elutes from the chromatographic system.
- **Type**: Classification of the peak.
- **Width [min]**: The width of the peak at its base in minutes.
- **Area [pA*s]**: Integrated area under the peak, representing the quantity of the compound.
- **Height [pA]**: Maximum height of the peak, indicating the concentration of the compound.
- **Area [%]**: Percentage of total area represented by the peak.

This data helps in identifying and quantifying the different components present in a sample.

### Chromatograph Analysis

**Description:**

The graph shown is a chromatograph with the following key components:

- **Title**: FID1 A, Front Signal (NO SAMPLE NAME (FRONT) 2020-05-16 18:48:13.D)
- **Y-Axis**: The signal intensity is measured in picoamperes (pA) with a range from 0 to 1,750,000 pA.
- **X-Axis**: The retention time measured in minutes (min) ranges from 0.0 to 1.0 minutes.

**Key Data Points:**

- Peaks are observed at specific retention times, indicating the presence of different compounds.
- The prominent peak occurs at a retention time of 0.494 minutes with the highest signal intensity.
- Smaller peaks are visible at retention times of 0.315, 0.346, 0.374, and 0.558 minutes.

**Analysis:**

This chromatogram represents the separation of components in a mixture, analyzed using a Flame Ionization Detector (FID). The most significant peak at 0.494 minutes likely corresponds to the primary compound in the sample, as it shows the highest signal intensity.

By comparing these retention times with those of known substances, the compounds present in the mixture can be identified and quantified. This process is crucial in various fields, including pharmaceuticals, environmental testing, and food safety, to ensure the purity and composition of products.
