◦ 35 yr

Question 2

Find the nuclear binding energy of potassium-40 (atomic mass = 39.9632591 amu) in units of joules per nucleon. [Data: neutron mass = 1.674928 × 10^–24 g; proton mass = 1.672623 × 10^–24g; electron mass = 9.109387 × 10^–28 g; N_A = 6.0221367 × 10²³ /mol; c = 2.99792458 × 10⁸ m/s]
◦ 1.37 × 10^–12 J/nucleon
◦ 5.48 × 10^–11 J/nucleon
◦ 5.64 × 10^–11 J/nucleon
◦ 1.41 × 10^–12 J/nucleon
◦ 2.97 × 10^–12 J/nucleon
