Comparing the density of neon and hydrogen under normal conditions, determine how many times the mass of a neon atom is greater than the mass of a hydrogen molecule.

1) To compare the densities of gases under normal conditions, we find their values in the density table ρ (Ne) = 0.8999 kg / m3, ρ (H2) = 0.08987 kg / m3. The density of neon ρ (Ne) is 0.8999 kg / m3 more than the density of hydrogen ρ (H2): 0.08987 kg / m3 ≈ 10 times.
2) To determine how many times the mass of a neon atom M (Ne) is greater than the mass of a hydrogen molecule M (H2), we find their masses in the periodic table. M (Ne) = 20.1797 amu, M (H2) = 2 x 1.00794 amu = 2.01598 amu The mass of a neon atom M (Ne) is greater than the mass of a hydrogen molecule at 20.1797 amu. : 2.01598 amu ≈ 10 times. Answer: the density and mass of neon is ≈ 10 times greater.
