The Radius $R$ Of a Nucleus of Mass Number $A$ Is Given By

question 10

Short Answer

The radius $R$ of a nucleus of mass number $A$ is given by $R = R _ { 0 } A ^ { 1 / 3 }$ , where $R _ { 0 } = 1.2 \times$ $10 ^ { - 15 } \mathrm {~m}$ , calculate the density of a nucleus that has contains 57 protons and 82 neutrons. The mass of a nucleon (proton or neutron) is $1.67 \times 10 ^ { - 27 } \mathrm {~kg}$ .
