6 Nuclear Reactions Fusion 2 1 H + 3 1 H 4 2 He + 1 0 n How much energy per mole of 2 1 H is produced?
7 Calculation of Fusion Energy How much energy per mole of 2 1 H produced? 2 1 H + 3 1 H 4 2 He + 1 0 n 2 1 H = 2.0141022 g/mol 3 1 H = 3.0160494 g/mol 4 2 He = 4.0026036 g/mol 1 0 n = 1.0086654 g/mol Δm = (4.0026036 + 1.0086654) g/mol - (2.0141022 + 3.0160494) g/mol = -0.0188826 g/reaction
