The molar mass and the mass of the substance give the moles of the substance. The 10-gram sample of neon (Ne) has the fewest atoms. Thus, option b is correct.
<h3>What are moles?</h3>
Moles of the substance are the ratio of the molar mass and the mass of the substance. The moles of each atom with respect to the Avagadro's number (Nₐ) is given as,
Moles = mass ÷ molar mass
- Moles of carbon (C) = 10 ÷ 12
= 0.83 Nₐ atoms
- Moles of neon (Ne) = 10 ÷ 20
= 0.5 Nₐ atoms
- Moles of fluorine (F) = 10 ÷ 19
= 0.52 Nₐ atoms
- Moles of nitrogen (N) = 10 ÷ 14
= 0.7 Nₐ atoms
- Moles of oxygen (O) = 10 ÷ 16
= 0.63 Nₐ atoms
Therefore, option b. 10 gm neon has the fewest atoms.

Answer:
any two
Explanation:
Gravitation force or gravitational attraction is a force of pulling or attraction that exist between any two bodies that have a mass. Each and every body attract each other with the force of gravity due to their masses.
Every object in this universe having mass and distance attracts every other object.

Answer:
2726.85 °C
Explanation:
Given data:
Initial pressure = 565 torr
Initial temperature = 27°C
Final temperature = ?
Final pressure = 5650 torr
Solution:
Initial temperature = 27°C (27+273 = 300 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
T₂ = P₂T₁ /P₁
T₂ = 5650 torr × 300 K / 565 torr
T₂ = 1695000 torr. K /565 torr
T₂
= 3000 K
Kelvin to degree Celsius:
3000 K - 273.15 = 2726.85 °C
