Question

What is the volume of 3 moles of methane (CH4)? (One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this question.)

20 L

22.4 L

44.8 L

67.2 L

Answer 1

For an ideal gas if we have 3mol of CH4 then it will occupy a volume of 22.4*3=67.2 L

So the answer is 67.2 L
Any questions please just ask. Thank u

Answer 2

67.2 L is the volume of 3 moles of methane.

Step-by-step 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:

`3* 22.4 = 67.2 L`

67.2 L is the volume of 3 moles of methane.
