    1. The problem statement, all variables and given/known data
    For the common isotope of nitrogen, 14N, calculate the mass defect.


    2. Relevant equations

    [tex]\Delta[/tex]M = Zmp + Nmn - M

    3. The attempt at a solution

    7(1.00727646688)+7(1.00866491560)-14.003074

    [tex]\Delta[/tex]M = .108516177


    Masteringphysics says this is wrong. says i may have made a rounding error? i have input three variations of this answer but all have been wrong.
