Corrosion is a natural process that converts a refined metal into a more chemically stable form . It is the gradual destruction of materials by chemical
Answer is: the average atomic mass of 125 atoms of uranium is 235.88.
ω(U-234) = 10 ÷ 125.
ω(U-234) = 0.080.
ω(U-235) = 75 ÷ 125.
ω(U-235) = 0.60.
ω(U-238) = 40 ÷ 125.
ω(U-238) = 0.320.
Average atomic mass of atoms of uranium =
Ar(U-234) · ω(U-234) + Ar(U-235) · ω(U-235) + Ar(U-238) · ω(U-238).
Average atomic mass of atoms of uranium =
234 · 0.08 + 235 · 0.6 + 238 · 0.32.
Average atomic mass of atoms of uranium = 18.72 + 141 + 76.16.
Average atomic mass of atoms of uranium = 235.88.
