  • Brad Sloan

    I scored 17 out of 30 (56.7%-Satisfactory) guessing on all the math questions.

  • The second to last qestion on the Dec I package. 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,

    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
