hi ,
radius of nucleus , R = (1.25 X10 ^-13 )* A ^1/3
= (1.25 X10 ^-13 )* 64 ^1/3
volume of nucleus V = 4/3 ¶ { (1.25 X10 ^-13 )* 64 ^1/3 } ^3
= 4/3 ¶ * 1.25 X 10 ^ -37 c.m.^3
volume of atom = 4/3 ¶ ( 1.0 X 10 ^-8) ^3
= 4/3 ¶ x 10 ^ -24 c.m. ^3
desired fraction = 4/3 ¶ * 1.25 X 10 ^ -37 / 4/3 ¶ x 10 ^ -24
= 1.25 X 10 ^-13 C )
