QUESTION 7 Iron-56 atoms have an actual mass of 55.9349 amu. Determine the mass deficiency of an iron 56 atom, and binding energy of a mole of iron-56 atoms OA. Am = 0.5268 amu, BE = 4.741x1013 Am = 0.5246 amu, BE = 1.574x1050 O Cam = 0.5302 amu, BE - 4.771x1013) OD. Am = 0.5302 amu, BE = 1.591x105 E Am = 0.5246 amu, BE = 4.721x1013 OF Am = 0.5246 amu, BE = 4 721x1018) OG Am -0.5302 amu, Be *4.771x1016) HOM05268 amu, BE =4.741x1016)

Answer 1

actual magd of Determine the mood deficiency have an question: Tpm - 56 atoms 55.9349 amu. of an iron-56 atom, and binding energy a mole of inon-56 am = 0.5268 amu,BR 24.741 x 10 B. am = 0.5246 OM atoms. AR x 1013 J omu BE = 1.574 x 105] Am 0.5302 amu, = 41771 x10,33 D. amu, BE = 1.591 X1053 E. om -0.5244 amy, BE = 4.721 x 1013 J F. sm 0.5246 amu, BE 4.721 X10"T om = 0.5302 amu, BE = 4.771 XLOJ om = 0.52 68 amo, B = 4.74 x 10165 - 0.53 02 11 S we have Ans: According to the question Calculate the total masa of of cron - 56 atoms. we know, masa of proton = 1.0078 amu maad of neutron = 1.0087 amu 30 Now iron-56 26 protons and neutrons. i mada of 26 protons = 26 X 1.00778 amu = 2.6.2028 amu 30 neutrons = 30 x 1.0087 amu mad of - 30.261 amu made of .. Total ison - 56 (Theoritical maad) =(26-2028 + 30.261) a = 56.4638 amy. am

NOW the actred mood of iron 56 atoms = 55.9399 amu, masa deficiency = thermitical madd- actual mand =156.4638 - 55.9 5.934,9] amu = 0.5289 amu 0 5302 amo X Now, binding energy - mada deficiency 931-5 mer = 0;5302 X 93115 MeV/ atom 493.8813 merlatom - 1493.8813 x 1.602 x10-13 J/arton = 493.08613 x 11.602x103) I x(6.023x1349) atom atoms mol 13 = 4.0765 x 10 J/mol 4.771 x 1013 J/mol so the correct answer is option - (Ans) and 2 o the ro options not matching to the calculated nearlts. So, option ane not A, B, D, E, F, G, H cornet. are
