The discussion revolves around converting a volume mixing ratio from [m3/m3] to [molecules/cm3], given specific conditions such as temperature (293K) and air density (1 kg/m3). The scope includes theoretical understanding and practical application of gas laws and conversions related to mixing ratios.
Participants express uncertainty regarding the conversion process and the necessary details required to perform it. There is no consensus on a specific method or solution, and multiple viewpoints on the approach to the problem are presented.
Participants highlight limitations in the information provided, including the need for additional details about the exercise and the relationship between volume mixing ratios and molecular counts.
Hi! Well not exactly. I know there is the ideal gas formula PV = nRT and that a mole contains the Avogadro number of molecules.Borek said:Do you know Avogadro's hypothesis?
And do you know how to convert gas volume to number of moles? Number of moles to number of molecules?
The volume mixing ratio can also be given in [mol/mol]. How do you convert a mol of gas into the number of molecules when only the air density and temperature are given?anuttarasammyak said:[m3/m3] has no physical dimension but [molecules/cm3] has physical dimension of L^-3. I am afraid some more details of the exercise are required to help you.
