Estimate the total binding energy for copper.
550 MeV

Estimate the energy, in joules, needed to break a 3.0g copper penny into its constituent nucleons.
E= in Joules

Please help me out I got 1st part I need the Energy in joules am confused please help me out...thanks

Number of atoms is
N= N(A)•m/μ =
=6.022•10ēģ•0.003/63.5•10⁻ģ=2.85•10ēē.
Number of nucleons (protons+neutrons) =
=2.85•10ēē•63=1.8•10ē⁴.
Energy = 1.8•10ē⁴•550•10⁶•1.6•10⁻đ⁹ =1.58•10⁸ J

Thanks for the help but 1.58x10^8 J is wrong n I recalculated you calculation I got 1.58x10^14 J but that was also wrong so could you plz help me out.
