The ideal gas law is defined as shown below:
pV = nRT

Where:
p: pressure
V: volume
n: number of moles
R: molar gas constant which is given by 8.31J mol-1K-1
T: temperature (Kelvin)

The formula is equal to the following:
pV / T = poVo / To
or

pV = NA · k · T

where:
NA: Avagadros constant which is given by n · NA = N
k: Boltzmanns constant which is given by k = R/NA = 1.38 · 10-23 JK-1
