What is the nuclear binding energy of an atom that has a mass defect of 5.0446
Use E = mc2. (Remember: The speed of light is approximately 3.00 x 10 m/s.)
10-29 kg?
5.61 x 10-45 J
1.51 x 10-20
4.54 x 10-123
1.78 x 1045 J

There is no answer that meets the final value of energy.

Maybe C. And you mistakenly put the 3 at the end.

Explanation:

Albert Einstein's equation of spatial relativity is the well-known E = mc2, which means that the energy of a body at rest (E) is equal to its mass (m) multiplied by the speed of light (c) at square. Einstein argued that the mass of a body is a measure of its energy content.

Now, if we know the mass of an atom, it is possible to find its energy.

E = 4.54 x10∧-12 k * m∧2 * s∧2

- Knowing that kg * m∧2 * s∧2 is the same as Joules then:

E = 4.54 x10∧-12 J
