Problem

The density of a lithium nucleus (A=7)(A = 7) is compared with that of a lead nucleus (A=208)(A = 208). The ratio ρLi/ρPb\rho_{\text{Li}}/\rho_{\text{Pb}} is closest to (a) 0.0337  (=7208)0.0337\;(=\dfrac{7}{208}) (b) 3.1  (=(208/7)1/3)3.1\;(=(208/7)^{1/3}) (c) 11 (d) 0.32  (=(7/208)1/3)0.32\;(=(7/208)^{1/3})
