How do I use this molar extinction coefficient?

Description : How do I use this molar extinction coefficient?

Last Answer : answer:Molar extinction coefficients are typically in M^-1* cm^-1 (aka 1/(M*cm)). If using a cuvette with a 1 cm path length, using the equation you give above the cm cancels and it gives you concentration in ... b = cm, cm cancels, and M^-1 is in the denominator and thus c is left to simply be M.

Do gases with high molar masses travel through small openings faster than gases with low molar masses?

Description : Do gases with high molar masses travel through small openings faster than gases with low molar masses?

Last Answer : answer:I wouldn’t think so, unless you include a propellant. Sorta like with the aerosol can. I don’t expect mass to matter much unless you’re driving the gas gravitically. All things being equal, I’d guess that you’re looking at the same rate of flow in both cases. But then, I’m no physicist.
