When a positron and an electron annihilate one another, the resulting mass is completely converted to energy. Calculate the energy associated with this process in kJ/mol. (I got 9.861 x 10^7 kJ per mol of reactant and that is wrong.)

An electron and a positron each have a mass of 9.11 ×
10-31 kg. They collide and both vanish, with only
electromagnetic radiation appearing after the collision. If each
particle is moving at a speed of 0.42c relative to the
laboratory before the collision, determine the energy of the
electromagnetic radiation.

2. Electron-positron annihilation A positron with kinetic energy equal to twice its rest mass energy is incident on an electron at rest The positron and electron annihilate creating two photons. One photon goes off at an angle of 30 with respect to the incident positron. Compute the energies of the two photons and find the direction in which the second photon travels

4. What is the ground-state energy of positronium, the bound state of an electron and positron? Hint: electron and positron have equal masses, so one cannot assume that one of the particles is at rest, while the other orbits around it. It is necessary to calculate using the reduced mass

An electron (rest mass me) of
energy E makes a head-on collision with a positron (positron is
electron’s antiparticle, it has the same mass as electron, but
opposite charge) In collision the two particles annihilate each
other and are replaces by two photons (γ rays) of equal energy,
each traveling at equal angles θ with electron’s direction of
motion. Find 1. The energy of each photon. 2. The momentum p of
each photon. 3. The angle θ.

Particle Physics
Let's do a little particle physics. Back in the '9os there was a large electron-positron collider at CERN in Geneva, Switzerland, called the "Large electron-positron collider," or LEP for short. (This collider was broken down and rebuilt into an even larger one that runs to this day, called the "Large hadron collider" or LHC.) It was LEP that discovered the W and Z bosons, which mediate weak nuclear processes like the beta decay of free neutrons Anyway, near...
