Answer:
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Mass of Cl₂ : 164.01 g
<h3>Further explanation</h3>
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :
![\tt n=\dfrac{N}{No}\\\\n=\dfrac{1.39.10^{24}}{6.02.10^{23}}\\\\n=2.31](https://tex.z-dn.net/?f=%5Ctt%20n%3D%5Cdfrac%7BN%7D%7BNo%7D%5C%5C%5C%5Cn%3D%5Cdfrac%7B1.39.10%5E%7B24%7D%7D%7B6.02.10%5E%7B23%7D%7D%5C%5C%5C%5Cn%3D2.31)
mass Cl₂(MW=71 g/mol) :
![\tt mass=mol\times MW\\\\mass=2.31\times 71=164.01](https://tex.z-dn.net/?f=%5Ctt%20mass%3Dmol%5Ctimes%20MW%5C%5C%5C%5Cmass%3D2.31%5Ctimes%2071%3D164.01)
Hi,
The answer is gravity.
The bigger the object is the more are other smaller objects attracted to it. The opposite of gravity is dark energy which keeps objects apart and accelerates expansion of the universe.
Hope this helps.
