Neon has an average atomic mass of 20.2 g/mol, whereas argon has an average atomic mass of 40.0 g/mol. how would the number of atoms in a 1.0 mol sample of neon compare to the number of atoms in a 4.0 mol sample of argon

Answer : The number of atoms in a 4.0 mole sample of argon has greater number of atoms or four times as compared to the number of atoms in a 1.0 mole sample of neon.

Explanation :

As we know that the 1 mole of substance contains number of atoms.

As per question,

The 1 mole sample of neon contains number of atoms.

And,

As, 1 mole sample of argon contains number of atoms

So, 4.0 mole sample of argon contains number of atoms

From this we conclude that, the number of atoms in a 4.0 mole sample of argon has greater number of atoms or four times as compared to the number of atoms in a 1.0 mole sample of neon.
