The person giving the answer below has put a lot of effort in, but the answer is not correct. The (approximate) answer is: 1.637 X 10-13 Joules.
Here's the correct working:
Electron and positron both have mass of about 9.109 X 10-31 kg.
So total mass, m = 2 x 9.109 x 10-31 kg.
The speed of light (in a vacuum) is c = 299,792,458 m/s.
E = mc2. So, put the numbers in the equation, use a calculator and you get the answer: about 1.637 x 10-13 Joules.
I am not a Physicist, I am merely a 9th grader.
However, it seems common sense to use Einstein's equation E=mc2 to solve this.
The energy produced upon an electron being annihilated would be E, and of course, m is the mass of the electron, then multiplied by the speed of light squared. What we'll do is:
E (in Joules)= (Mass of electron in grams) * Speed of light in meters squared
A quick Wikipedia search reveals the mass of the electron is
9.10938291(40) * 10-31 kg
Which I typed into my Scientific Calculator and returned,
3.643753164 * 10-29 kg
I then moved the decimal to the left (10 has a negative exponent) 29 times to get,
0.0000000000000000000000000003643753164 kg.
Now, E=mc2 calculates mass in grams. So we must get rid of three of the zeros:
0.0000000000000000000000003643753164 g
There. We now have the mass of the electron in grams. The positron, as you probably know, has the exact same mass. Now to find the speed of light in meters...
According to Google, the speed of light is: 299 792 458 m/s.
We must square it, and we get:
8.987551787 * 1016
Which translates to,
89875517870000000
So now, we have both the mass of the electron/positron AND the speed of light squared! Lets multiply them!
3.274842026 * 10-08 J (Joules).
There you go.
0.0000003274842026 J.
Not much, isn't it?
But the other day, using the same equation, I (mentally) collided 100g of Hydrogen with 100g of Anti-Hydrogen and got over 17.9 quintillon joules!
I just love physics!

What is Annihilation in terms of nuclear processes?
When a nucleus of U-235 or PU-239 fissions, a small amount of mass is lost and appears as energy, by virtue of E = mc2. This I would call annihilation, not the actual fissioning itself which gives rise to two other nuclei.
What is the end product of matter-antimatter annihilation?
The end product of matter-antimatter annihilation is energy in the form of photons (light particles) or other subatomic particles.
Where does dissipated energy go as in matter and anti-matter annihilation?
In matter-antimatter annihilation, the energy is primarily transformed into high-energy photons (gamma rays). These photons can then further interact and create new particles in a process called pair production or contribute to heating the surrounding environment. Ultimately, the energy from matter-antimatter annihilation is dispersed and can contribute to various physical processes.
How does the process of quark antiquark annihilation contribute to the creation of high-energy particles in particle physics?
In particle physics, the process of quark-antiquark annihilation contributes to the creation of high-energy particles by converting the mass energy of the quark and antiquark into new particles. This process releases a large amount of energy, which can result in the formation of high-energy particles such as mesons or photons.
What is the relationship between the creation and annihilation operators in quantum field theory?
In quantum field theory, creation operators add energy and particles to a system, while annihilation operators remove energy and particles. They work together to describe the behavior of particles in a field.

In both cases energy is released through annihilation of mass

Calculate the efficiency of glycolysis if 12 kcal of energy are required to transfer energy from glucose to ATP?
To calculate the efficiency of glycolysis, first determine the total energy input from the glucose molecule that is available for ATP production. Next, determine the actual energy produced in ATP molecules. Finally, divide the energy produced by the total input energy and multiply by 100 to get the efficiency as a percentage.

What happens during the process of neutron-antineutron annihilation?
During neutron-antineutron annihilation, a neutron and an antineutron collide and are converted into energy in the form of gamma rays, mesons, and other particles. This process releases a large amount of energy and results in the destruction of the neutron and antineutron.

How do you calculate kinetic energy of the photoelectron emitted from the surface?
To calculate the kinetic energy of a photoelectron emitted from a surface, you can use the equation: ( KE = hf - \phi ), where ( KE ) is the kinetic energy of the photoelectron, ( h ) is the Planck constant, ( f ) is the frequency of the incident photon, and ( \phi ) is the work function of the material.
