hi  I'm stuck on a question...
use the graph to calculate the binding energy of uranium 235 nucleus: the graph gave 7.6MeV i need to give my answers to GeV  and the mark scheme told me to 7.6Mev x 235 to give 1.8GeV?? i thought you just multiplied by 10^3. what happened? thanks!

Are you sure that the graph didn't show binding energy per nucleon?

but even if you multiplied it by 235, giving the total binding energy, it's still in MeV i did 7.6x10^6 x 235 x 10^3 which gave 1.8x10^12...which is waay too big

a question on converting MeV to GeVi got the answer
