Enter the sum of the reactants (amu) and the product of the masses (amu) into the Calculator. The calculator will evaluate the Nuclear Q Value.

## 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.

- First, determine the sum of the reactants (amu).
- Next, determine the product of the masses (amu).
- Next, gather the formula from above = Q = (mr – mp) * .9315.
- Finally, calculate the Nuclear Q Value.
- 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
