# The graph shows the average binding energy per nucleon, \(E_b/A\), in \(\text{MeV/nucleon}\), as a function of mass number \(A\) for stable nuclei. A heavy nucleus with mass number \(A = 220\) undergoes fission into two identical daughter nuclei, each with mass number \(A = 110\). Based on the graph, what is the total energy released during this fission event?

The graph shows the average binding energy per nucleon, \(E_b/A\), in \(\text{MeV/nucleon}\), as a function of mass number \(A\) for stable nuclei. A heavy nucleus with mass number \(A = 220\) undergoes fission into two identical daughter nuclei, each with mass number \(A = 110\). Based on the graph, what is the total energy released during this fission event?

![A graph of binding energy per nucleon \(E_b/A\) in \(\text{MeV/nucleon}\) versus mass number \(A\). The horizontal axis is labeled Mass Number, \(A\), with major tick marks at 0, 50, 100, 150, 200, 250. The vertical axis is labeled Binding Energy per Nucleon, \(E_b/A\text{ (MeV/nucleon)}\), with major tick marks from 0 to 10 in increments of 2. A smooth curve begins near the origin, rises rapidly to a broad maximum around \(A = 56\) with a value of approximately \(8.8\text{ MeV/nucleon}\), and then gently decreases at higher mass numbers. Two points on the curve are highlighted with solid dots and dashed projection lines to both axes: the first point is at \(A = 110\) with \(E_b/A = 8.5\text{ MeV/nucleon}\), and the second point is at \(A = 220\) with \(E_b/A = 7.7\text{ MeV/nucleon}\). No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785826337-4rap0x.jpg)

- **A.** \(0.8 \text{ MeV}\)
- **B.** \(176 \text{ MeV}\)
- **C.** \(935 \text{ MeV}\)
- **D.** \(3564 \text{ MeV}\)
