The shape of hydrogen atom is 0.5Â. Find the volume of 1 mole hydrogen atoms in m^3

Question

It's is related to physics. It is Based on a

Vogadro's hypothesis 

Answer 1

The RADIUS of the H atom is about 0.5 angstroms.

 

Although the shape of the atom is spherical, assume it occupies a cube whose side is twice the radius.  Find the volume of the cube, and multiply it by Avogadro's number.

 

V = L³A₀ = [2(0.5 angstroms)]³ (6.02 x 10²³) = ?

 

This gives volume in angstroms³, which you can convert to m³ using

 

1 angstrom = 10^-10 m
