Homework Statement


What is the molar binding energy of the carbon 12 nuclei?


Homework Equations


e=mc2


The Attempt at a Solution


proton mass = 1.00728u
neutron mass: 1.00866u

before: 6p+6n = 12.09564u
after: carbon 12 = 12u
delta m = 0.009564u

E=mc2
=(.009564u)(9x10^16kJ/g)

now I don't know what to do, you can convert u and g to the same unit but they cancel out, so how do I get kJ/mol

Your equation above is the energy per atom. How many atoms per mole?

I'm getting 8.6 not 8.9 now... Carbon 12 is 12...
