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
