What is value of R in PV nRT?
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as:
R = 8.314 J/mol·K
.

Why is R the universal gas constant?
The value of gas constant
R is same for all gasest and is independent of the nature of gas
. Hence it is called universal gas constant.
What is the physical significance of universal gas constant R?
It's
a proportionality between energy and temperature
. In the ideal gas law, it relates temperature on the right to the product of pressure and volume, which is an energy.
What is the value of R at STP?

What does R equal in math?
R in maths is equal to
real numbers
. R is used as a mathematical symbol for the representation of real numbers.
What is the PV nRT?
A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combination of the gas laws of Boyle, Charles, and Avogadro.
What is the T in PV nRT?
PV = nRT is an equation used in chemistry called the ideal gas law equation. t = (
PV)/(nR
).
How do we get 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.
How do you convert gas constant to R?
so
R = PV/nT
or we can say R equals (pressure × volume) / (amount of gas × temperature). We know that temperature can be in Celcuius , Fahrenheit and Kelvin. For pressure we use units like atm, kPa and mmHg (torr).
Is gas constant the same for all gases?
Value of specific gas constant is not constant. Its value of r changes from gas to gas.
Value of universal gas constant (R) is same for all gases
.
What is the dimensional formula of gas constant?
