The Ideal Gas Law it relates the amount of a gas (in moles) to its pressure, volume and temperature. The Ideal Gas constant will vary depending on the units of pressure used, see below. Enter three known values to get the fourth. You may enter as many digits as you wish. Then select the desired units
-
P = Pressure
-
V = Volume
-
n = Number of mols
-
R = Ideal Gas Constant
-
T = Temperture
Three of the four values must be known to find the fourth. Here are these formulas.
Find P, V, n & T:
The Universal Gas Constant
This will vary depending on the units of pressure used.
