A "neon" sign contains 2.4¡Ñ10^2mL of argon. Assuming that the gas is at standard temperature and pressure, there is 1.00 moles of gas per 22.4 L of volume. How many argon atoms are present in this sign?

use the convention; 22.4L = 1.00moles
so convert that volume of argon in neon sign to liters and fine the mole for that volume using the above convention.
then use this; 1 mole = 6.02e23 atoms to find the number of atoms in the mole you calculated above.
