Assuming STP, one mol of oxygen (64 grams) would be 22.4 L.
So divide 1 by 22.4 and that's how many mols you have. Multiply by 64 grams and there's your mass of one Liter. It'd be useful to convert to kg now, just multiply by 10^(-3)
Weight is mass multiplied by the acceleration of gravity. Assuming this is on earth, acceleration is 9.8.
So final answer should be 28*10^(-3) kgm/s^2==>.028 Newtons
If you want pounds, multiply by 0.2248 to get 0.0062944
Should be right, although I'm not sure. I'm mixing physics and chemistry...unless you wanted mass, not weight, then ignore everything after mass.
EDIT: Just wanted to point out a mistake in the answer above...he forgot that oxygen gas is O2. Weight of one mol of O is 32 g, but molecular weight of one mol of O2 is 64 g.
2nd EDIT: Just realized...I was wrong, Maussy right. Atomic weight of oxygen is 16, so molecular weight of O2 is 32 g. I didn't even look at a periodic table; I was thinking of sulfur. Sorry for any confusion.

22.4 dm3 is 1 mol. So 1 L of O2 weighs 1.4285g

At 0°C , a mole of oxygen i. e. 32g correspond to 22.4l . This is due to Avogadro's law and is correct for all gases
So 1l of oxygen weights 32/22.4 =1.42 g

1 liter is 1000cm3 in r.t.p That is 1 dm3. 24dm3 is 1 mol. So, 1 liter of oxygen gas is 0.0417 mol. That weighs 1.3344g
