Answer is: the average atomic mass is 232.

ω₁ = 20% ÷ 100%.

ω₁ = 0.20.

ω₂ = 80% ÷ 100%.

ω₂ = 0.80.

Ar₁ = 120 (number of protons) + 120 (number of neutrons).

Ar₁ = 240.

Ar₂ = 120 + 110 .

Ar₂ = 230.

Average atomic mass of atoms of bolognium =

Ar₁ · ω₁ + Ar₂ · ω₂.

Average atomic mass of atoms of bolognium = 240 · 0.2 + 230 · 0.8.

Average atomic mass of atoms of bolognium = 48 + 184.

Average atomic mass of atoms of bolognium = 232.
