3. 12 . 4532 MeV 4. 20 . 8976 MeV 5. 172 . 453 MeV 6. 17 . 3445 MeV correct Explanation: Let : m H = 1 . 00782 u , m Li = 7 . 016 u , m He = 4 . 0026 u , and c 2 = 931 . 5 MeV / u . Q = (Δ m ) c 2 = ( m H + m Li - 2 m He ) c 2 = [1 . 00782 u + 7 . 016 u - 2 (4 . 0026 u)] × (931 . 5 MeV / u) = 17 . 3445 MeV .
