Ventilation - steady state concentration....3.0 pints/hour. I'm confused how this equation works..without any units. the number 24.45...is that L/Mol? Thanks Jason ----------------------------- Jason, You are correct, the units for Molecular Volume are L/mol Molecular volume = L/mol = V/n = 24.45 @ NTP = RT/P This is all using the ideal gas equation PV=nRT Thanks for asking, George The second to last qestion on the Dec I package.

Jason,

You are correct, the units for Molecular Volume are L/mol

Molecular volume = L/mol = V/n = 24.45 @ NTP = RT/P
This is all using the ideal gas equation
PV=nRT

Thanks for asking,

George
