    5.6L

    Explanation:

    Given parameters:

    number of moles = 0.25mol

    pressure on gas = 1atm

    temperature = 273K

    Gas constant R = 0.0821Latm/molK

    Unknown:

    Volume of gas = ?

    Solution:

    Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

    It is mathematically expressed as;

    PV = nRT

    where P is the pressure

    V is the volume

    R is the gas constant

    T is the temperature

    n is the number of moles

    All the parameters are in the appropriate units and we simply solve for the volume of the gas;

    1 x V = 0.25 x 0.0821 x 273

    V = 5.6L
