Question: What Is The R In PV NRT?

What is the constant R?


The gas constant R will appear in many contexts as this is a Universal constant that relates energy and temperature.

A pressure times a volume is an energy.

As such, you will also encounter the gas constant R in typical energy units of Joules.


What is the value of R in CGS unit?

R = 8.314462618… kg⋅m2⋅s−2⋅K−1⋅mol−1.

What is the value of R in PV NRT?

R has the value 0.082057 L⋅atm/mol⋅K with the above units for the remaining variables.

What is the R value in ideal gas law?

What is r in PV NRT for mmHg?

The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K. R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.

How do you use PV NRT?

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. Or you could think about the problem a bit and use PV=nRT. N2O is placed in a piston.

What is the accepted value of R?

0.0821 LQuestion: The Accepted Value For R In The Ideal Gas Law Is 0.0821 L*atm/mol*K.
