The first step is write a balanced equation for the combustion of ethanol

C2H5OH + 3 O2 => 2 CO2 + 3 H2O

conversion factors:

One mole of any gas will, at STP, be have the volume 22.4 L. (memorize this)

3 moles of Oxygen per mole ethanol. (got this from the equation above)

Work:

2.5 mol ethanol * 3 (mol Oxygen/mol ethanol) => 7.5 mol Oxygen

7.5 mol Oxygen * 22.4 (L/mol oxygen) => 168 L

hope this helps,
