From the given data, the amount of energy required to break the nucleus of aluminium Al1327Al 1327 is __________x×10−3Jx \times {10}^{- 3}J

Mass of neutron =1.00866u= 1 . 00866u
Mass of proton =1.00726u= 1 . 00726u
Mass of Aluminium nucleus =27.18846u= 27 . 18846u
(Assume 1u1u corresponds to xJxJ of energy)
(Round off to the nearest integer)

Correct answer

0

Step-by-step solution

\Deltam=(ZmP+(A−Z)mn)−MAl\Deltam = \left(Z{m}_{P} + ( A - Z ) {m}_{n}\right) - {M}_{Al}

=(13×1.00726+14×1.00866)−27.18846= ( 13 \times 1 . 00726 + 14 \times 1 . 00866 ) - 27 . 18846

=27.21562−27.18846= 27 . 21562 - 27 . 18846

=0.02716u= 0 . 02716u

E=27.16x×10−3JE = 27 . 16x \times {10}^{- 3}J
