The atomic masses of neutron, proton, electron 232 Pu and 231 Pa are given. Using these values, the change in energy when 1 mole of 232 Pu nuclei and 1 mole of 231 Pa nuclei are formed from their respective number of protons and neutrons is to be calculated. Concept introduction: The difference between the mass of an atom and the mass of its constituent particles is known as mass defect. This mass can be converted into energy by Einstein’s mass-energy equation as, Δ E = Δ m c 2 To determine: The change in energy when 1 mole of 232 Pu nuclei and 1 mole of 231 Pa nuclei are formed from their respective number of protons and neutrons.

Chapter 18, Problem 43E
Interpretation Introduction

Interpretation: The atomic masses of neutron, proton, electron 232Pu and 231Pa are given. Using these values, the change in energy when 1 mole of 232Pu nuclei and 1 mole of 231Pa nuclei are formed from their respective number of protons and neutrons is to be calculated.

Concept introduction: The difference between the mass of an atom and the mass of its constituent particles is known as mass defect. This mass can be converted into energy by Einstein’s mass-energy equation as,

ΔE=Δmc2

To determine: The change in energy when 1 mole of 232Pu nuclei and 1 mole of 231Pa nuclei are formed from their respective number of protons and neutrons.
