If we have 16 gm of Oxygen gas at 273 C and 1 atm pressure, what would be its volume?
The same as the volume of its container.
However, if you had such a quantity of gas in a piston, it would occupy a volume of approx.
How do I know this? The molar volume of an ideal gas is
We thus have
And using the molar volume of an Ideal Gas at standard pressure,
