The calculated mass of $_{20} Ca^{40}$ is $40.328 u$ . It releases $306.3 MeV$ energy in a nuclear process. Its isotopic mass is

Options:

Answer:

Solution:

$BE = Δ m \times 931 MeV$ $306.3 = Δ m \times 931$ $Δ m = 0.3290$ $Δ m =$ calculated mass $-$ isotopic mass - Isotopic mass $= Δ m -$ calculated mass $= ∴ Isotopic mass 0.3290 - 40.328 = - 39.998 = 39.998$
