Given that 1 amu=1.661x10-24 g, what is the weight in atomic mass units of an atom weighing 4.125x10-22 g?
The unified atomic mass unit, denoted u, is defined to be 1 u = 1.6605 × 10-27 kg. It can be used as an approximation for the average mass of a nucleon in a nucleus, taking the binding energy into account. How much energy, in megaelectron volts, would you obtain if you completely converted a nucleus of 15 nucleons into free energy?

Post-lab Questions Part 2 8. Among the elements, hydrogen has the least massive atoms. An atom of hydrogen has an average mass of 1.66 x 10-24 g. This mass is very small, but remember it is only one atom which is composed of one proton and one electron! What is the relative mass of hydrogen if it is the least massive element? 9. How do the atomic masses found on the periodic table compare to the relative masses you calculated?...
