- How much energy in kJ is released to form one mole of 75As from protons, electrons, and neutrons if the nucleus has a mass of 74.921594 amu? The masses of the proton, electron and neutron are 1.00728 amu, 0.000549 amu and 1.00867 amu, respectively. -3.15e10 kJ/mol -6.31e10 kJ/mol -6.31e13 kJ/mol 3.15e13 kJ/molQ4 Natural Uranium, as found on earth, consists of two isotopes in the ratio of ^ 235 U/ ^ 238 U=0.07 Assuming that these two isotopes existed in equal amounts at the time the earth was formed; calculate the age of the earth. [note: life times: ^ 238 U=6.52*10^ 9 years , ^ 235 U=1.02*10^ 9 years](a) Energy is required to separate a nucleus into its constituent nucleons, as the drawing indicates; this energy is the total binding energy of the nucleus. In a similar way one can speak of the energy that binds a single nucleon to the remainder of the nucleus. For example, separating nitrogen 7N¹6 into 7N15 and a neutron takes energy equal to the binding energy of the neutron. Find the energy (in MeV) that binds the neutron to the 7N¹6 nucleus by considering the mass of 7N 15 (atomic mass = 15.000108 u) and the mass of on¹ (atomic mass = 1.008665 u), as compared to the mass of 7N ¹6 (atomic mass = 16.006099 u). (b) Similarly, one can speak of the energy that binds a single proton to the 7N¹6 nucleus. Following the procedure outlined in part (a), determine the energy (in MeV) that binds the proton (atomic mass = 1.007825 u) to the 7N¹6 nucleus. The atomic mass of carbon 6C15 is 15.010599 u. (c) Which nucleon is more tightly bound, the neutron or the proton? (a) Number (b) Number i…
