Question #ec345

Answer 1

You gots `"palladium"` and `"silver"`.......

Explanation:

The only way you can do this is to look up the isotopic distribution of each metal. Rhodium is out of consideration because it is `100%` `""^103Rh`. Silver is likely because it is approx. `50%` `""^107Ag`, and `""^109Ag`, and you gots peaks of equal magnitude at `m/e=107,109*"amu"`.

So that leaves peaks at `"104, 105, 106, 108, 110"` for which to account, and this fits the isotopic profile for palladium metal.

This question was poorly conceived, inasmuch as the percentage distribution is WRONGLY attributed. The percentages add up to 200% not 100% as is appropriate for a mass spectrum. You could probably use the given percentages to intuit that the peaks at `m/e=107,109*"amu"` constitute one metal, and the remaining peaks constitute another metal, i.e. both sets must add up to 100%. C'est la vie.
