🤓 Based on our data, we think this question is relevant for Professor Norman's class at UARK.

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.

We’re being asked to calculate the energy released for the reaction of a positron and an electron :

${}_{\mathbf{+}\mathbf{1}}{}^{\mathbf{0}}\mathit{e}\mathbf{+}{}_{\mathbf{-}\mathbf{1}}{}^{\mathbf{0}}\mathit{e}\mathbf{\to}\mathbf{2}\mathbf{}{}_{\mathbf{0}}{}^{\mathbf{0}}\gamma $

To calculate the energy released for the reaction, we’re going to use the following steps:

*Step 1**: Calculate the mass defect (Δm).***Step 2**: Calculate the mass defect (Δm) in kg.**Step 3**: Calculate the energy released (E).

**Step 1: Calculate the mass defect (Δm).**

**Given:**
