Answer 2

Answer: C. The argon sample would have four times as many atoms as the neon sample.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

1 mole of neon $Ne$ contains=$6.022\times 10^{23$ atoms

1 mole of argon $Ar$ contains=$6.022\times 10^{23$  atoms

Thus 4 moles of argon $Ar$ contains=$\frac{6.022\times 10^{23}}{1}\times 4=24.09\times 10^{23}$  atoms

Thus the argon sample would have four times as many atoms as the neon sample.
