How do you get R in PV nRT?

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. Be sure to convert whatever units you start with into the appropriate units when using the ideal gas law.

What is the R constant in the ideal gas law?

It is a physical constant that is featured in many fundamental equations in the physical sciences, such as the ideal gas law, the Arrhenius equation, and the Nernst equation. As a consequence, the value of the gas constant is also exactly defined, at precisely 8.J⋅K−1⋅mol−1.

What is r in the ideal gas law equation?

R has the value 8.314 J/(K·mol) ≈ 2 cal/(K·mol), or 0.0821 l·atm/(mol·K).

How do you solve for t in PV NRT?

Rewrite the equation as nRt=PV n R t = P V . Divide each term by nR and simplify. Divide each term in nRt=PV n R t = P V by nR n R .

How do you derive the ideal gas equation?

PV = nRTP is the pressure of the ideal gas.V is the volume of the ideal gas.n is the amount of ideal gas measured in terms of moles.R is the universal gas constant.T is the temperature.

What is the ideal gas law used for?

The ideal gas law relates the four independent physical properties of a gas at any time. The ideal gas law can be used in stoichiometry problems in which chemical reactions involve gases. Standard temperature and pressure (STP) are a useful set of benchmark conditions to compare other properties of gases.
