If One Mole of Oxygen-16 Were Formed from Protons and Neutrons,0.1366

question 21

Multiple Choice

If one mole of oxygen-16 were formed from protons and neutrons,0.1366 g of mass would be lost.What can best account for this loss?

• A)When fission occurs,the nuclei remaining always has a smaller mass.
• B)Converting from the atomic scale (in amu's)to the macroscopic scale (in grams)can often cause minor errors to occur.
• C)The process was so exothermic,the system lost energy,which meant that it also lost mass.
• D)This is impossible because of the Law of Conservation of Matter (so mass must be conserved).
• E)Both A and C are correct.
