Hello everyone! Please see the question below.

'Determine the molecular formula for each of the following:
...
d. an amide that has a molecular ion with an m/z value of 115' (From Organic Chemistry (7^th edition) by Bruice)

I worked out the question and my answer is C₆H₁₃NO. But the solution manual reads C₆H₁₂NO. Do anyone know how to do the question?

I think this may just be a typo. From the nitrogen rule you can see that the number of hydrogens must be odd.
