    Answer:

    \boxed {\boxed {\sf 0.5 \ moles}}

    Explanation:

    At standard temperature and pressure (STP), 1 mole of any gas has a volume of 22.4 liters. This applies to oxygen, so let’s create a proportion.

    \frac {1 \ mol}{22.4 \ L}

    Since we are trying to find the moles in 11.2 liters, we should multiply by that number.

    11.2 \ L *\frac {1 \ mol}{22.4 \ L}\\

    The units of liters cancel.

    11.2 *\frac {1 \ mol}{22.4 }

    Condense into 1 fraction.

    \frac {11.2 }{22.4 } \ mol

    0.5 \ mol

    At STP, 11.2 liters of oxygen gas is equal to 0.5 moles of oxygen gas.
