## 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**
