Question
One mole of carbon dioxide contains
- 6.02 × 1023 atoms of carbon
- 6.02 × 1023 atoms of oxygen
- 6.02 × 1023 atoms of water molecule
- 6.02 × 1023 atoms of hydrogen
Hint:
One mole of any molecule = 6.02 
1023 atoms of one element
The correct answer is: 6.02 × 1023 atoms of carbon
One mole of any element = Avogadro number of atoms = 6.02 1023 atoms
One mole of any molecule = 6.02 1023 atoms of one element
One mole of carbon dioxide contains 6.02 1023 atoms of Carbon & 2 6.022 1023 atoms of oxygen
