Answer:
67.2 L is the volume of 3 moles of methane.
Explanation:
Moles of methane gas = 3 mol
Given that 1 mol of any gas occupies 22.4 l of of volume under certain conditions of temperature and pressure.
Then volume occupied by 3 mol of meta he gas will be:
[tex]3\times 22.4 = 67.2 L[/tex]
67.2 L is the volume of 3 moles of methane.
