Hypofluorous acid, HOF, is very unstable, decomposing in a first-order reaction to give HF and O 2

Question:

Hypofluorous acid, HOF, is very unstable, decomposing in a first-order reaction to give HF and O₂, with a half-life of 30. minutes at room temperature:

HOF(g) → HF(g) + 1⁄2 O₂(g)

If the partial pressure of HOF in a 1.00-L flask is initially 1.00 × 10² mm Hg at 25°C, what are the total pressure in the flask and the partial pressure of HOF after exactly 30 minutes? After 45 minutes?
