I'm sorry if it's a lot, but I want to make sure I didn't do any mistakes on this worksheet. Thanks!!1. If the mass of a Ne-20 atom is 19.9924 amu, calculate its binding energy. (I got 2.578 x 10^-11 Joules)2. If the mass of a Ca-40 atom is 39.9626 amu, calculate its binding energy. (I got 5.4876 x 10^-11 Joules)3. Calculate the binding energy per nucleon for He-4. (I had no idea how to do this one...does anyone have any ideas??)4. If the binding energy per nucleon for U-235 is 7.5702 MeV, which can offer the greater amount of energy per mass unit: He-4, or U-235? (I got He-4)Does anyone spot any mistakes above? Thanks soooo much for helping!!!
