Quick Answer: What Is The R Value For MmHg?

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 bar?

If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.

What is r in the ideal gas law equation answers com?

What is ideal gas constant r? It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).

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.

What is R 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.

What is the R in PV NRT?

PV. nR. P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•K T = Temperature (Kelvin) The correct units are essential.

What is the R value in the ideal gas law?

U.S. Standard Atmosphere. The U.S. Standard Atmosphere, 1976 (USSA1976) defines the gas constant R∗ as: R∗ = 8.31432×103 N⋅m⋅kmol−1⋅K−1. Note the use of kilomole units resulting in the factor of 1,000 in the constant.

What is the value of the gas constant R in units of mmHg ⋅ cm 3 mol ⋅ K?

Its value in S.I. unit is 8.314 J/K*mol. It is also known as universal gas or ideal gas constant. The energy value incorporated in the value of ‘R’ is the product of the pressure-volume product.
