Tritium (1H3) is a rare isotope of hydrogen that can be produced by the fusion reaction ZX1

Question:

Tritium (1H3) is a rare isotope of hydrogen that can be produced by the fusion reaction ZX1 + 1Y → 1H3 + Y
The atomic messes are ZX1 (1.0087), 1 YA (2.0141u), 1H3(3.0161u). Determine the (a) atomic mass number A, and (b) the atomic number Z. (c) Using the masses given in the reaction, determine how much energy (in MeV) is released by this reaction?
