What is the mass of 1.6 × 10 21 neon atoms?

The mass of one mole (6.022 × 10^23 atoms) of neon is approximately 20 grams. Therefore, the mass of 1.6 × 10^21 neon atoms can be calculated by setting up a proportion: (1.6 × 10^21 atoms / 6.022 × 10^23 atoms) * 20 g = 0.053 g, which rounds to 0.054 g.
