To find the average velocity of atoms in neon at 278 K, we can use the equation for the root mean square speed (v_rms) given by (v_{rms} = \sqrt{\frac{3kT}{m}}), where (k) is the Boltzmann constant ((1.38 \times 10^{-23} , \text{J/K})), (T) is the temperature in Kelvin, and (m) is the mass of a neon atom in kilograms. The molar mass of neon is approximately 20.18 g/mol, which converts to (3.34 \times 10^{-26} , \text{kg}) per atom. Plugging in the values, the average velocity of neon atoms at 278 K is approximately 394 m/s.

What is the average velocity of atoms in 1.50 mol of neon at 278 k?
To find the average velocity of atoms in a gas, we can use the formula for the root mean square speed ( v_{rms} = \sqrt{\frac{3kT}{m}} ), where ( k ) is the Boltzmann constant, ( T ) is the temperature in Kelvin, and ( m ) is the mass of a single atom. For neon, the molar mass is approximately 20.18 g/mol, which equates to approximately ( 3.34 \times 10^{-26} ) kg per atom. At 278 K, plugging in the values gives an average velocity of about 400 m/s.
Does a mole of neon atoms weigh the same as a mole of aluminum atoms?
No. Think of it this way - say you had 20 basketballs and 20 bowling balls. Will the basketballs weigh the same as the bowling balls? No, because an individual basketball weighs less than a bowling ball, so if you have equal numbers of them, they aren't going to weigh the same. Now take 6.02 × 1023 atoms (one mole) of neon and 6.02 × 1023 atoms of aluminum. One atom of neon is going to weigh less than one atom of aluminum, so equal numbers of them aren't going to weigh the same.
What is the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure?
The ratio of the average velocity of hydrogen molecules to neon atoms is the square root of the ratio of their molar masses. Since the molar mass of neon is about 20 times that of hydrogen, the average velocity of hydrogen molecules would be about √20 times faster than that of neon atoms.

Why is one mole of argon less than one mole of neon?
One mole of argon has a lower atomic mass compared to one mole of neon, as argon has a higher atomic number and thus heavier atoms. This means that there are more argon atoms in one mole compared to neon, but since each argon atom is heavier, the overall mass is less.
