1.	The nucleus of an atom can be assumed to be spherical. The radius of the nucleus of mass number A is given by 1.25xx10^(-13) xx A^(1//3) cm Radius of atom is one Å. If the mass number is 64, Then the fraction of the atomic volume that is occupied by the nucleus is
Answer» `1.0xx10^(-3)` `5.0xx10^(-5)` `2.5xx10^(-2)` `1.25xx10^(-13)` Solution :Radius of nucleus = `1.25xx10^(-13) XXA^(1//3) cm` `=1.25xx10^(-13) xx 64^(1//3) =5xx10^(-13)` cm Radius of ATOM =1Å=`10^(-8)` cm `"Volume of nucleus"/"Volume of atom"=((4//3)pi(5xx10^(-13))^3)/((4//3)pi(10^(-8))^3)` `=1.25xx10^(-13)`
