Q
How many atoms are in CuSO4?
A
There are 6 atoms in one molecule of CuSO4: 1 copper atom, 1 sulfur atom, and 4 oxygen atoms.
Breaking down the molecular composition:
- Cu = 1 copper atom
- S = 1 sulfur atom
- O₄ = 4 oxygen atoms
- Total = 6 atoms
If considering the common pentahydrate form (CuSO4·5H2O):
- CuSO4 = 6 atoms
- 5H2O = 5 × 3 = 15 atoms (10 hydrogen, 5 oxygen)
- Total = 21 atoms in CuSO4·5H2O
Important Notes:
- Anhydrous CuSO4 contains 6 atoms
- Pentahydrate contains 21 total atoms
- Subscripts indicate atom quantity
- Each molecule has this fixed composition
