Assume that protons and neutrons have equal masses. Mass of a nucleon is 1.6×10⁻²⁷ kg and radius of nucleus is 1.5×10⁻¹⁵A^1/3 m. The approximate ratio of the nuclear density and water density is n×10¹³. The value of n is .

Question

Accepted Answer

11. ρ=(3m)/(4π R₀³)=(3×1.6×10⁻²⁷)/(4π×3.375×10⁻⁴⁵)=1.13×10¹⁷ kg m⁻³ Ratio to water (10³): 1.13×10¹⁴=11.3×10¹³ → 11
