Air has mass and density, and. cold air is denser than warm air.
The same amount of water as oil air
L
mol/dm³ is measure for molarity
Add an alkaline compound to raise the pH to 7.2.
Since we know that one mole of any gas at STP is equal to 22.4 L we can multiply 135L by the following conversion: 1 mole/22.4L. When you set up the problem it looks like this…: (135L)x 1 mole/22.4L =6.03 moles of oxygen gas The liters cancel out and you are left with moles as your units.
So your answer is then 3.058
