Final answer:
The compound C₇H₅(NO₂)₃ consists of a total of 24 atoms from 4 different elements: carbon, hydrogen, nitrogen, and oxygen.
Step-by-step explanation:
The compound C₇H₅(NO₂)₃ comprises multiple elements, which can be counted by examining the chemical formula. Each molecule contains 7 carbon (C) atoms, 5 hydrogen (H) atoms, and 3 nitro groups (NO₂), with each nitro group consisting of 1 nitrogen (N) and 2 oxygen (O) atoms. Therefore, the total number of elements in one molecule of this compound is:
- Carbon (C): 7 atoms
- Hydrogen (H): 5 atoms
- Nitrogen (N): 3 atoms (1 from each NO₂ group)
- Oxygen (O): 9 atoms (2 from each NO₂ group)
Summing these up, we get a total of 24 atoms from 4 different elements comprising the compound C₇H₅(NO₂)₃.
