Answer: Not possible to find average amu with only the information provided.

Explanation:

Is there more information about the other isotopes? I don't see how one could calculate an overall atomic mass with only one isotope is known. An isotope of 186.956 with abundance of 62.6% isn't enough information. We're not told anything about the other isotopes: are they larger, smaller, and at what percentage. If one has an amu of 204.956 at 37.4%, the overall atomic mass would be quite different than if it had an atomic mass of 182.956 at 37.4%. More infornmation is required.
