SUMMARY
The mass defect of the 40Ca nucleus is calculated using the formula Δm=(Zmp+(A-Z)mn)-m, where Z is the atomic number, A is the mass number, mp is the mass of a proton, mn is the mass of a neutron, and m is the actual mass of the nucleus. The initial calculation yielded a mass defect of 0.242 amu, but the correct mass defect is 0.367 amu. The discrepancy was resolved by adjusting the formula to Δm=(Zmp+(A-Z)mn)-(m-Zme), where Zme accounts for the binding energy correction.
