The answer is: 1.5 moles of oxygen are present.

V (O₂) = 33.6 L; volume of oxygen.

p (O₂) = 1.0 atm; pressure of oxygen.

T = 0°C; temperature.

Vm = 22.4 L/mol; molar volume at STP (Standard Temperature and Pressure).

At STP one mole of gas occupies 22.4 liters of volume.

n (O₂) = V (O₂) : Vm.

n (O₂) = 33.6 L : 22.4 L/mol.

n (O₂) = 1.50 mol; amount of oxygen.
