I need help with this ideal gas law stoichiometry question.

I don't know how to solve this. The answer is 1.2 atm but I want to know why that is. I searched up the question online for hours and they all say it's 1.2 atm but don't give any explanation.
I screenshotted the problem.

The problem is a bit ambiguous.
The hydrogen peroxide concentration is usually given in % by weight.
The square brackets in the Table suggest a molar concentration. With this concentration, using the reaction equation, the molar volume at 300 K, and the Boyle-Mariotte Law, you get the result without a calculator.

Assuming it is a molar concentration: how many moles of H2O2 decomposed? How many moles of oxygen were produced?
