What is the volume of 2 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.)

44.8 L

Explanation:

One mole of any gas occupies 22.4 L under standard temperature (0°C = 273 K) and standard pressure (1 atm). Under those same conditions, the volume occupied by 2 moles of methane, assuming ideal behavior is:

2 mol * (22.4 L / 1 mol) = 44.8 L

2 moles of methane under STP occupy a volume of 44.8 L.

The volume of 2.0 moles of CH4 is 44.8 L

Explanation:

Step 1: Data given

An ideal gas that contains 1 mol occupies 22.4 L under standard conditions.

Step 2: Calculate volume for 2 moles of methan (CH4)

1 mol = 22.4 L

2 mol = X L

V1 / n1 = V2 / n2

⇒ V1 = the volume of 1 mol CH4

⇒ n1 = number of moels CH4 = 1.0 mol

⇒ V2 = the volume of 2.0 mol CH4 = X

⇒ n2 = the number of moles CH4 = 2.0

22.4 L / 1 = X / 2

X = 2*22.4 = 44.8 L

The volume of 2.0 moles of CH4 is 44.8 L
