Final answer:
If pressure is measured in pascals and volume is measured in liters, the unit for the ideal gas constant (r) will be (Pa * L) / (mol * K).
Step-by-step explanation:
The molar gas constant is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, rather than energy per temperature increment per particle.
The ideal gas constant (R) does not have specific units. The units of R depend on the units used for pressure, volume, and temperature in the ideal gas equation. It is expressed as R = 8.314 J/mol • K while using atmospheres as your unit of pressure.
In this case, when pressure is measured in pascals (Pa) and volume is measured in liters (L), the units of R would be:
(Pa * L) / (mol * K).
