Answer:
[tex]2.96 \times 10^{25}[/tex] atoms.
Explanation:
- 1 mol of [tex]H_2O[/tex] has [tex]2 N_A = 1.20 \times 10^{24}[/tex] atoms of H inside. This is because in one mol of the molecule there are two atoms of hydrogen.
- 24.3 mol of [tex]H_2O[/tex] has [tex]x[/tex] atoms of Hydrogen inside.
[tex]x = 1.2044 \times 10^{24} \times 24.3 = 2.96 \times 10^{25}[/tex]
Extra:
- [tex]N_A[/tex] is the Avogadro's Number, which is equal to [tex]6.022 \times 10^{23}[/tex] atoms, the value of one mol.
