The volume occupied by 5.40 mole of O2 is 120.96 L.
The term molar volume refers to the volume of one mole of a gas. According to Professor Avogadro, the volume of one mole of a gas is 22.4 L.
Now, we are asked to find the volume of 5.40 mole of O2.
If 1 mole of O2 occupies a volume of 22.4 L
5.40 mole of O2 occupies 5.40 mole * 22.4 L/1 mole = 120.96 L
The volume occupied by 5.40 mole of O2 is 120.96 L.
