PV=nRT 32 gram O2 = 1 mole O2
(1atm)(V) = (1 mole)(.0821)(273)
V = 22.4 L
If the two occupy the same volume, 25 grams is denser.
If it remains sealed the volume remains the same.

grams per liter is a measurement of density. A milliliter is a measurement of volume. They are not the same.
A 'real' gas would occupy a higher volume as compared to the same amount of gas would have when 'idealistically' calculated by the 'ideal' gas law. The 'eigen' volume (its own molecular dimension) is to be taken in account at high pressure.
If the two occupy the same volume, 25 grams is denser.
lead and water will occupy the same volume. however the Density of lead is 207.2 g/L (grams per liter) and the Density of H2O is only 18.02 g/L so if you had the same volume of lead and water the lead would be heavier. But if you had the same Weight of both water and lead the water would have a larger volume.
The density of a material does not change with mass. 100 grams of a material will occupy 10 times the volume of 10 grams of the same material.
12 grams of water is equal to 12,000 mg of water and is the same as 12,000 ml of water.
If it remains sealed the volume remains the same.
Volume = how much space an object occupies, that nothing else can occupy at the same time.
The density of water, for example is the mass divided by the volume. So if a litre of water weighs a kilogram and the volume is a litre, then the density one kilogram per litre. This is the same as saying 1000 grams per litre, or 1000 grams per 1000 millilitres, or one gram per millilitre since 1000 grams = one kilogram, and 1000 millilitres = 1 litre
mass involves weight....volume is size. A ballon and a loaf of bread may have the same volume (occupy the same space) , but the bread has more volume.
Volume = how much space an object occupies, that nothing else can occupy at the same time.

Gases always have the most volume. A pan full of water will occupy 2 quarts or 2 liters. That same pan of water boiled until it became steam would occupy a whole room.
The Martian satellite Deimos has a volume of 999.78 km3 which means it would take about 108 million Deimos sized objects to occupy the same volume as the Earth.
