Bonjour, svp aidez-moi pour cet exercice. Merci beaucoup d'avance.​

Réponse:

1.

∆m = m(Helium) + m(neutron) - m(deuterium)-m(tritium)

∆m = 6,64466.10-²⁷ + 1,67493.10-²⁷ - 3,34358.10-²⁷ - 5,00736.10-²⁷

∆m = - 3,135.10-²⁹ kg

2.

E = |∆m|c²

E = 3,135.10-²⁹ × (2,9979.10⁸)²

E = 2,818.10-¹² J

3.

Emol = N(A) × E

Emol = 6,02.10²³× 2,818.10-¹²

Emol = 1,70.10¹² J
