Question

The questions below refer to the following:
Iron-56,

, has a binding energy per nucleon of 8.79 MeV. (1 MeV = 1.60 * 10^-¹³ J)
-Determine the amount of energy needed to "decompose" 1 mol of iron-56 nuclei.

Quizplus · Accepted Answer

The correct answer is A.The energy needed to decompose 1 mol of iron-56 nuclei is 4.74 x 10^13 J. This can be calculated using the equation E = mc^2, where E is energy, m is mass, and c is the speed of light. The mass of 1 mol of iron-56 is 55.845 g, and the speed of light is 2.998 x 10^8 m/s. Plugging these values into the equation gives E = (55.845 g) x (2.998 x 10^8 m/s)^2 = 4.74 x 10^13 J.
