Each of four flasks is filled with a different gas. Each flask has the same volume, and each is filled to the same pressure, 3.0 atm, at 25°C. Flask A contains 116 g of air, flask B has 80.7 g of neon, flask C has 16.0 g of helium, and flask C has 160. g of an unknown gas.
(a) Do all four flasks contain the same number of gas molecules? If not, which one has the greatest number of molecules?
(b) How many times heavier is a molecule of the unknown gas than an atom of helium?
(c) In which flask do the molecules have the largest kinetic energy? The highest rms speed?
