m/z 204 206 207 208
relative intensity 0.287 4.51 4.32 10.00
Idenitfy the species responsible for the peak at m/z 208
what does this mean??

m/z = molecular mass; it's the mass over charge(which is always +1 unless you have a +2 spectrum graph).
the one furthest to the right is 9 times out of 10 the parent ion (ie the non-fragmented ion). The only time it isn't is if there are isotopes present.
Assuming the 208 peak is the furthest right, the species responsible for that would just be the parent ion which should/could be stated in the question.

Oh right, thank you! So the parent ion would just be Pb? As that's what the data is from?

Uh I would think it's an isotope of Pb since lead's atomic mass is 207. but yeah the parent ion is Pb but that peak is at 207.

not Pb, [Pb]+.
