Based on the data provided in the table, the solubility of a substance generally increases with an increase in the temperature of the solvent. Here, we have four samples dissolved in water at different temperatures.
Here are the temperatures for each sample:
1. Sample 1: 80°C
2. Sample 2: 45°C
3. Sample 3: 55°C
4. Sample 4: 63°C
To determine which sample most likely had the highest solubility, we look for the sample with the highest temperature because higher temperatures usually indicate higher solubility.
Comparing the temperatures:
- Sample 1: 80°C
- Sample 2: 45°C
- Sample 3: 55°C
- Sample 4: 63°C
The highest temperature is 80°C, which corresponds to Sample 1.
Therefore, the sample that most likely had the highest solubility is:
1.
