Answer : The number of atoms of argon are [tex]1.61\times 10^{25}[/tex]
Explanation : Given,
Moles of argon = 26.8 moles
As we know that,
1 mole of substance always contains [tex]6.022\times 10^{23}[/tex] number of atoms.
As, 1 mole of argon contains [tex]6.022\times 10^{23}[/tex] number of atoms
So, 26.8 mole of argon contains [tex]26.8\times 6.022\times 10^{23}=1.61\times 10^{25}[/tex] number of atoms.
Therefore, the number of atoms of argon are [tex]1.61\times 10^{25}[/tex]
