l2mol {marelac} | R Documentation |
Converts from liter to moles for a gas
l2mol(x=1, T=25, P=1, a=0, b=0)
x |
Volume of the gas, liter |
T |
Temperature, dg celsius |
P |
Pressure, atmosphere |
a |
Species-specific coefficient, dm^6*bar/mol^2 |
b |
Species-specific coefficient, dm^3/mol |
mol
the coefficients a and b are species-specific; values of 0 in general give good estimates
Some values of a and b:
He | 0.034598 | 0.023733 | |
H2 | 0.24646 | 0.026665 | |
N2 | 1.3661 | 0.038577 | |
oxygen | 1.3820 | 0.03186 |
