We’re being asked to calculate the binding energy in MeV per nucleon of an atom of ^{49}K has a mass of 48.965514 amu.

To calculate the binding energy released use the following steps:

*Step 1**: Calculate the mass of K from its subatomic particles (neutrons and protons).***Step 2**: Calculate the mass defect (Δm).**Step 3**: Calculate the energy released (E).

**Step 1: Calculate the mass of K from its subatomic particles (neutrons and protons) or the theoretical mass.**

**Given:**

An atom of ^{49}K has a mass of 48.965514 amu. Calculate the binding energy in MeV per NUCLEON.

the masses:

mass of ^{1}H atom = 1.007825 amu

mass of a neutron = 1.008665 amu

1 amu = 931.5 MeV

Give your answer to 4 significant figures and DO NOT use E notation. No charity points will be awarded.

a. 930.8 MeV

b. 84.23 MeV

c. 0.1756 MeV

d. 8.424 MeV

e. 412.7 MeV
