There is no such software. You can calculate the molecular
weight by yourself, then add 1Da (H+) to it. That is what you
usually expect to see from MS analysis. Sometimes, you will
see sodium adduct, instead of proton adduct. In that case,
you have to add 23Da to the molecular weight.
There are some programs to calculate the isotopic pattern
for a molecule. That can help you a little. Just search
"isotopic pattern" in google and you should be able to
find quite a few.
