One of the hopes for solving the world's energy problem is

tomake use of the fusion reaction:

How much energy is released when one mole ofdeuterium is fused

with one mole of tritium according to the abovereaction? The masses

of the atoms and the neutrons are:

2H = 2.0140 amu 3H = 3.01605 amu

4He = 4.002603 amu 1n = 1.008665 amu

The speed of light is 2.9979x108m/s.

2.803013439419911 * 10⁻¹² J

Explanation:

Mass defect = mass of reactant - mass of product

(2.0140 + 3.01605) - (4.002603 + 1.008665)

5.03005 - 5.011268 = 0.018782 amu

mass in Kg = mass (amu) * 1.66053892173 * 10⁻²⁷ kg

mass in kg = 0.018782 * 1.66053892173 * 10⁻²⁷ = 3.1188242027932 * 10⁻²⁹kg

E = Δm c² where c is the speed of light = 2.9979 * 10⁸m/s

E = 3.1188242027932 * 10⁻²⁹kg * (2.9979 * 10⁸m/s) ² = 2.803013439419911 * 10⁻¹² J
