How do I compute the +2 charge state m/z for a peptide of 4731.3 Da?

Details up front: +2 · 4731.3 Da.

This should be a straightforward calculation and I keep getting two different answers.

The numbers are arbitrary; the method is what I am after.

Can someone show the working rather than just the answer?
