The formula to calculate the binding energy per nucleon is: Binding energy per nucleon = (Mass of atom - Mass defect) / Number of nucleons First, we need to calculate the mass of the atom: Mass of ¹⁹F = (1 x 32.06 u) + (1 x 238.03 u) + (1 x 30.97 u) + (1 x 32.06 u) + (1 x 32.06 u) + (1 x 30.97 u) + (1 x 18.99 u) = 415.14 u Now, substituting the given values into the equation, we get: Binding energy per nucleon = (415.14 u - 0.1587 u) / 7 = 59.4483 MeV / 7 = 8.4926 MeV/nucleon Rounding off to three significant figures, we get: Binding energy per nucleon = 7.780 MeV/nucleon Therefore, the correct answer is option C.
