SUMMARY
The mass defect of the 15N nucleus is calculated by subtracting the mass of its constituent nucleons from the actual mass of the nucleus. The correct calculation involves using the mass of 15N, which is 15.000109 u, rather than the mass of 14N (14.003074 u). The mass defect is determined using the formula: mass defect = (mass of protons + mass of neutrons) - mass of nucleus. The accurate mass defect for the 15N nucleus is approximately 1.120161 u.
