Plutonium's Atomic Mass is 244,064 204 (5) because the only naturally occurring isotope is 244Pu. Interestingly, we manufacture or synthesize a much more of other isotopes.
The atomic mass of the most important isotope of plutonium (239Pu) is:
239,052 1634 (20).
The atomic number of plutonium is 94. For the mass of other isotopes see the link below.
Atomic masses are from the tables of Audi, Wapstra and Thibault (AME 2003).
