Estimate the total number of molecules inclusive of oxygen, nitrogen, water vapour and other constituents in a room of capacity 30m^(3) at a temperature of 30^(@)C and 1 atmosphere pressure.

Estimate the total number of molecules inclusive of oxygen, nitrogen,

1.	Estimate the total number of molecules inclusive of oxygen, nitrogen, water vapour and other constituents in a room of capacity 30m^(3) at a temperature of 30^(@)C and 1 atmosphere pressure.
Answer» SOLUTION :At Boltzmann.s CONSTANT, `k_(B)=R/N,R=k_(B)N` Now, `PV=nRT=nk_(B)NT` `THEREFORE` The number of molecules in the room, `nN=(PV)/(k_(B)T)=(1.013xx10^(5)xx25)/(300xx1.38xx10^(-23))` The number of molecules in the room `=6.117.xx10^(26)`
