Question 579: Atoms & Nuclei

Question

A certain mass of Hydrogen is changed to Helium by the process of fusion. The mass defect in fusion reaction is 0.02866 u. The energy liberated per u is (given 1 u = 931 MeV)

Accepted Answer

Mass defect $$\Delta $$m = 0.02866 a.m.u.
Energy = 0.02866 ÃÂ 931 = 26.7 MeV
