What is the total mass of 3.01 x 10^23 atoms of helium gas?

2 g

Moles of atom =  atoms / 6.022 × 10^23  

Therefore; number of moles;

=(3.01 ×10^23) / (6.022 × 10^23)

= 0.5 moles

But;

Mass = moles of atom × Molar Mass of Helium  

Thus total mass of helium:

= 0.5 × 4

= 2 g

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
