**What is the constant R value in PV nRT?**

Specifically, R is equal to the ratio PV/nT. The exact numerical value of the gas constant actually varies with the chosen units. The numerical value of R as 8.3144598 is a result of the specific units we use. This value of R is a result of measuring the physical magnitudes of gases in the standard SI units.

### Can you do PV nRT with mmHg?

Note the different value and unit for R, to be in agreement with using mmHg for the pressure unit. Alternatively, you could convert 780. mmHg to atm and then use 0.08206 L atm / mol K for the value of R….Solution:

**Why is the gas constant R?**

The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as Ideal gas constant or molar gas constant or universal gas constant.
