If a nucleus had a diameter of 8.0 × 10^-15 m, what would its mass be in atomic mass units? A)7 B)296 C)37 D)64 E)128

Question

Quizplus · Accepted Answer

The mass of a nucleus can be estimated using its volume and the average nuclear density. The volume of a sphere is given by V = (4/3)πr³, where r is the radius. The radius here is 4.0 × 10⁻¹⁵ m. The average nuclear density is approximately 2.3 × 10¹⁷ kg/m³. Using these, the mass can be calculated and converted to atomic mass units (1 amu = 1.66 × 10⁻²⁷ kg), resulting in approximately 37 amu.
