    Option A = 2.2 L

    Explanation:

    Given dа ta:

    volume of one mole of gas = 22.4 L

    Volume of 0.1 mole of gas at same condition = ?

    Solution:

    It is known that one mole of gas at STP occupy 22.4 L volume. The standard temperature is 273.15 K and standard pressure is 1 atm.

    For 0.1 mole of methane.

    0.1/1 * 22.4 = 2.24 L

    0.1 mole of methane occupy 2.24 L volume.

    2,2 L

    Explanation:

    Under normal conditions of temperature and pressure: 273 K and 1 atm. The formula is used:

    PV = nRT

    R = Regnault constant

    1 atm x V = 0,1mol x 0,082 l atm/K mol x 273 K

    V = (0,1mol x 0,082 l atm/K mol x 273 K) / 1 atm

    V = 2,2368 l
