Answer:
Density of the He atom = 12.69 g/cm³
Explanation:
From the information given:
Since 1 mole of an atom = 6.022x 10²³ atoms)
1 atom of He =
The volume can be determined as folows:
since the diameter of the He atom is approximately 0.10 nm
the radius of the He = = 0.05 nm
Converting it into cm, we have:
Assuming that it is a sphere, the volume of a sphere is
=
=
=
Finally, the density can be calcuated by using the formula :
D = 12.69 g/cm³
Density of the He atom = 12.69 g/cm³
