Answer 1

Based on the provided data, the compounds in the given locations can be identified as follows:

1. Blood: Caffeine with the empirical formula C8H12N2O3
2. Face: Unable to determine compound identity without oxygen data
3. Stomach: Unable to determine compound identity without oxygen data
4. Pockets (2000 tablets): Unable to determine compound identity without oxygen data
5. Blood: Unable to determine compound identity without oxygen data
6. Pockets: Unable to determine compound identity without oxygen data
7. Pockets: Unable to determine compound identity without oxygen data
8. Pockets: Unable to determine compound identity without oxygen data
9. Pockets: Unable to determine compound identity without oxygen data
10. Pockets: Unable to determine compound identity without oxygen data
11. Pockets: Unable to determine compound identity without oxygen data
12. Pocket: Unable to determine compound identity without oxygen data
13. Pocket: Unable to determine compound identity without oxygen data
14. Pocket (in syringes): Unable to determine compound identity without oxygen data

It seems that the compound identities in some locations cannot be determined due to missing data on the oxygen content.
