The question does not specify what z is so this answer could be completely wrong. However, if the question is in the context of the standard Gaussian distribution, the answer is 0.493613 (to 6 dp)
0.5m-1
Perhaps if you read the question properly, you would not have to ask the question!
That's a Gaussian distribution.
Surface area of a sphere: A = 4πr2So, surface area = 4pi52

divide 0.108 gm by 1 coulomb of charge because e.c.e equals mass in gm/charge
Surface area equals 864cm2
127.5

No.
0.6 m-1 is the ratio of surface area to volume for a sphere.
That's a Gaussian distribution.
zero .. such an atom is neutral. No net charge
0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.
The answer depends on what measure - volume, surface area - equals 375.
