Verified answer

r= pv/(nt)

p: 1 atm or 760 torr (or mmHg) or 101.325 kPa

v: 22.4 L liter

n: 1 mol

t: 273 Kelvins

so, you have either 0.0821 atm*L/(mol * K)

this is the most common one

for the others, just plug in the correct units.

Hope this helps.

R is a constant, called the ideal gas constant. You can find all values for R in Wikipedia under "Gas Constant". You choose the units for R that match the units you've measured P and V in.

Some commonly used values are:

8.314472 J · K-1 · mol-1

0.0820574587 L · atm · K-1 · mol-1

62.3637 L · mmHg · K-1 · mol-1

With the addition of Avogadro's law, this gave way to the

* ideal gas law

PV = nRT \,,

where

P is the pressure (SI unit: pascal)

V is the volume (SI unit: cubic meter)

n is the number of moles of gas

R is the ideal gas constant (SI: 8.3145 J/(mol K))

T is the thermodynamic temperature (SI unit: kelvin).

(The law works with any consistent set of units, provided that the temperature scale is zero at absolute zero, and the proper gas constant is used.)

An equivalent formulation of this law is:

PV = NkT \,

Search for gas constant, or if you know P (atm) V(L) n (mole) and T (Kelvin)

R = PV/nT ==> units are atm•L/K•mole

here's the actual value: http://en.wikipedia.org/wiki/Gas_constant

R is a constant that equals approx. .08206 L-atm/mol-K

When using the ideal gas law, you must have units of P, V, T, and n in atmospheres, liters, Kelvin and mol, respectively.

perfect gas regulation basically works on gasses with specific characteristics. the perfect gas regulation assumes that the molecules do no longer attrat one yet another, have not have been given any mass, etc. this does not carry real under specific situations, like at temperatures on the portion of absolute 0 (the gas molecules reveal charm at such low temperatures)

we have,pv=nrt

or,r=pv/nt

=1atm*22.4litres/1*273degreeA

=0.082 ltr atm per degree absolute tempr per mole

hope this helps,

r = PV/nT

r is a constant

is is 8.314

try.. ntpv = r

hehe..
