Question
Two flasks A and B have equal to volumes. Flask A contains H2 and is maintained at 300K while the flask B contains an equal mass of CH4 gas and is maintained at 600K. Which flask contains a greater number of molecules ? How many times?
Solution
The number of molecules of a gas is proportional to the number of moles.
Let the mass of each gas in the two flasks be = mg
Molecular mass of H2 = 2
Molecular mass of CH4 =16
Thus, the number of molecules of H2 in the flask. A will be eight times the number of molecules of CH4 in flask B.
