To find the number of neon atoms, first calculate the moles of neon in 1.00 L using its density (0.900 g/L) and molar mass (20.18 g/mol). Then, multiply the moles by Avogadro's number (6.02 × 10^23 atoms/mol) to find the number of atoms. This calculation results in approximately 2.69 × 10^22 atoms.
