What is the fraction of the hydrogen atom's volume that is occupied by the nucleus? the bohr radius is 0.529×10−10m?

Volume of a sphere = 4/3 x pi x r^3

When put a fraction of volume constant 4/3 x pi cancels out.

So only cube of radii remains.

Radius of proton = 10^-15 m (Fact; remember it)

Radius of total Hydrogen atom = 0.529 × 10^−10 m

Fraction of Volumes : R'^3/R^3 = (R/R)^3

Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =

6.755 x 10^-15

u i forgot the answer?

the answer is 0.42 is that is an option. this question provides no info
