well first you need to know how much pressure is being exerted on the bag and the temperature that the oxygen is at.
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
Divide 225ml by 20.9, then multiply by 100.
The volume is 64,8 L.
By freezing the volume increase.
Yes, if the large plastic bag had the same volume as the original container and was rigid enough to sustain the same pressure.
It will be a quart.
oxygen is used ... volume decreases.
To estimate the volume of the pot.
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
it increase as a result of pressure generated from the heat
About 20% of the volume of the air in the room is oxygen.
Oxygen
20 cups
Divide 225ml by 20.9, then multiply by 100.
liters
The volume is 64,8 L.
Depends upon whether it's wood or plastic; plastic's possibly more denser.
