Answer:
2,198,081,377,400,000,000,000,000 atoms
Explanation:
Avogadro's number = 6.02214076 × [tex]10^{23}[/tex]
One mole of any element, including atoms, is Avogadro's number of them.
H2O = 18g/mol
Mass → Moles and Moles → Atoms
65.8g/18g/mol = 3.65 moles of H2O
3.65 moles x 6.02214076 × [tex]10^{23}[/tex] = 2,198,081,377,400,000,000,000,000 atoms
