Q: What is the value of R in the ideal gas equation PV=nRT?
Solution: R can have different values depending on the units used, including 0.0821 L·atm/(K·mol), 8.314 J/(K·mol), and 62.36 L·mmHg/(K·mol).
Steps: 5
Step 1: Understand the ideal gas equation, which is PV = nRT.
Step 2: Identify what each letter in the equation represents: P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
Step 3: Recognize that R (the gas constant) can have different values depending on the units used for pressure, volume, and temperature.
Step 4: Learn the common values of R: 0.0821 L·atm/(K·mol) for atmospheres, 8.314 J/(K·mol) for joules, and 62.36 L·mmHg/(K·mol) for millimeters of mercury.
Step 5: Remember that you need to use the correct value of R based on the units you are using in your calculations.
