Answer:
The average pressure in the container due to these 75 gas molecules is
Explanation:
Here Pressure in a container is given as
Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below
Here
mass is to be calculated for 75 gas phase molecules as
Volume of container is 0.5 lts
So density is given as
- is the mean squared velocity which is given as
Here RMS is the Root Mean Square speed given as 605 m/s so
Substituting the values in the equation and solving
So the average pressure in the container due to these 75 gas molecules is
