Answer: 0.84 atmosphere
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..
All these units of pressure are inter convertible.
We are given:
Pressure of the gas = 640 mmHg
Converting this unit of pressure into 'atm' by using conversion factor:
[tex]760mmHg=1atm[/tex]
[tex]640mmHg=\frac{1}{760}\times 640=0.84atm[/tex]
Thus there will be 0.84 atm.
