Isotopes and Atomic Mass Lab Report Questions 1: binding energy is the energy required to hold the nucleus together To calculate the binding energy; E=mc2 M= the difference in mass in(kg), between what’s measured and what’s expected by adding up the component’s protons and neutrons. C= the speed of light squared Mass defect = predicted mass – observed mass M= 6.6978*10^-27 – 6.646*10^-27 = 5.18*10^-29Kg Convert from Kg to J E=m*c^2

5.18*10^-29 * (3*10^8)2

5.18*10^-29 * 9*10^16 = 4.662*10^-12J

Question 3: By a system called beta decay, C decays. An atom of 14C decays into an atom of 14N during this process, during which one of the neutrons in the carbon atom becomes a proton. This raises the number of protons in the molecule by five, forming a nitrogen atom instead of a carbon atom.

Question 4: 215x present at 25% and 217x presents at 75% 215*25/100 + 217* 75/100 = 215*0.25 +217*0.75 =53.75+162.75 =216.5 amu.

Question 5: average mass of chlorine listed in the periodic table: 35.453

kanakrieh 2 Number of chlorine-35 atoms:10 Number of chlorine-37 atoms:3 Weighted average calculated in simulation: 35.43amu Question 6: Number of chlorine-35 atoms:10 Number of chlorine-37 atoms:3 Weighted average calculated in stimulation: Question 7: 0.7577*34.969 + 0.2423*36.996= 35.453amu

Questions8: mg-24=23.9850 Mg-25=24.9858 Mg-26=25.9826 23.9850+24.9858+25.9826/3=24.984amu...
