Questions & Step-by-Step Solutions
Which of the following represents the ideal gas constant? (2022)
Step 1: Understand what the ideal gas constant (R) is. It is a number used in the ideal gas law equation, which relates pressure, volume, temperature, and amount of gas.
Step 2: Know that the ideal gas constant can be expressed in different units. The two common forms are R = 0.0821 L·atm/(K·mol) and R = 8.314 J/(K·mol).
Step 3: Remember that L·atm/(K·mol) is used when dealing with gases in terms of liters and atmospheres, while J/(K·mol) is used in terms of energy (joules).
Step 4: Recognize that both forms of R are correct, but they are used in different contexts depending on the problem you are solving.
