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?
From a physical standpoint, the gas constant is
a proportionality constant that related the energy scale to the temperature scale for a mole of particles at a given temperature
. Units for the gas constant vary, depending on other units used in the equation. One common value is 8.3145 J/mol·K.

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 F value?
The F value in regression is the
result of a test where
the null hypothesis is that all of the regression coefficients are equal to zero. In other words, the model has no predictive capability.
What does PV nRT solve?
The
ideal gas law
can also be written and solved in terms of the number of moles of gas: PV = nRT, where n is number of moles and R is the universal gas constant, R = 8.31 J/mol ⋅ K. The ideal gas law is generally valid at temperatures well above the boiling temperature.
