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

  1. A39.998
  2. B40.6570
  3. C0.3290
  4. D2.85 10⁴

Correct answer

A. 39.998

Step-by-step solution

BE = m 931 MeV 306.3= m 931 m=0.3290 m= calculated mass - isotopic mass - Isotopic mass = m- calculated mass aligned =& 0.3290-40.328 &=-39.998 Isotopic mass &=39.998 aligned
