Nuclear Q Value Formula

Q = (mr - mp) * .9315

Variables:

• Q is the Nuclear Q Value (GeV)
• mr is the sum of the reactants (amu)
• mp is the product of the masses (amu)

To calculate Nuclear Q Value, subtract the product of the masses from the sum of the reactants, then multiply by .9315.

How to Calculate Nuclear Q Value?

The following steps outline how to calculate the Nuclear Q Value.

1. First, determine the sum of the reactants (amu). 
2. Next, determine the product of the masses (amu). 
3. Next, gather the formula from above = Q = (mr – mp) * .9315.
4. Finally, calculate the Nuclear Q Value.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

sum of the reactants (amu) = 2.748

product of the masses (amu) = 1.24
