Precise measurements give the following masses:
nuclide mass
particle
mass
2.0141 u
1.0086649 u
3.0161 u
-je 5.4858 x 10¯* u
He

on
released
absorbed
Is energy released or absorbed by this reaction?
O neither released
nor absorbed
I need more
information to
decide.
If you said energy was released or absorbed, calculate
how much energy is released or absorbed.
Give your answer in both kJ/mol and MeV. Round each
of your answers to 3 significant digits.
OkJ/mol
O Mev
Note: take particular care to keep enough digits in any
intermediate calculation, and use enough digits in any
scientific constants you need, since the data with which
you are working are very precise.
