Answer
The average volume added is 24.60 mL.
Explanation
To calculate the average volume added, we need to follow these steps:1. **Identify the Relevant Data**: Extract the volume measurements from the titration experiments, excluding the trial titration result.2. **Sum the Volumes**: Add together the volumes of the valid titrations.3. **Count the Valid Titrations**: Determine the number of valid titration measurements.4. **Calculate the Average**: Divide the total volume by the number of valid titrations.5. **Round the Result**: Round the average volume to two decimal places.Let's assume the following volumes were recorded in a series of titration experiments (excluding the trial titration result):- Titration 1: 24.50 mL- Titration 2: 24.70 mL- Titration 3: 24.60 mL### Step-by-Step Calculation:1. **Sum the Volumes**:
2. **Count the Valid Titrations**:
3. **Calculate the Average**:
4. **Round the Result**: The average volume is already at two decimal places.
