    A. 0.0821 L-atm / mol-K

    Explanation:

    Ideal gas law is given as,

    PV = nRT

    R is termed as Universal gas constant.

    Under standard conditions of Temperature (273 K), Volume (22.4 L), pressure (1 atm) and for number of moles (n=1), we will get R as,

    R = 1 atm * 22.4 L / 1 mol * 273 K

    = 0.0821 L-atm / mol-K
