In diatomic molecule, the distance between the centers of two atoms is 1.22 [tex]\AA[/tex].
Converting [tex]\AA[/tex] to m:
Since, 1 [tex]\AA[/tex]=[tex]10^{-10} m[/tex]
Thus,
1.22 [tex]\AA[/tex]=[tex]1.22\times 10^{-10} m[/tex]
Now, Converting m to feet:
1 m=3.28 feet
Thus,
[tex]1.22\times 10^{-10} m=1.22\times 10^{-10}\times 3.28 feet=4\times 10^{-10}feet[/tex]
Therefore, distance in feet is [tex]4\times 10^{-10}[/tex]
