In the equation PV = nRT, what are the units of R when P is in atm and V in liters?
A.L·atm/(mol·K)
B.J/(mol·K)
C.cal/(g·°C)
D.mol·K/(L·atm)
Explanation
Core Concept
R = PV/(nT) carries the units of the quantities it connects: L·atm divided by mol·K, numerically 0.08206. Matching units is why R takes different values in other unit systems.
Correct Answer
AL·atm/(mol·K)
