Calculating Neutron Binding Energy in 13-C

[MeKnos]

Homework Statement

Calculate the binding energy of a neutron in 13-C.

Homework Equations

mass defect= (Z*mp) + (N*mn) - (mc13)
B = mass defect * conversion factor
B/(Z+N) = Binding Energy per Neutron

I wasn't given any values for the numbers, so I wiki'd them.

The Attempt at a Solution

B= 6(1.0078) + 7(1.0087) - 13.0033 = .1044
B= .1044 * (931.49) = 97.2 MeV
B/13 = 7.49 MeV

thats wrong, and so is B/7=13.89 MeV
