At a constant temperature, a gas occupies a volume of `200 mL` at a pressure of `0.720"bar"`. It is subjected to an external pressure of `0.900"bar"`. What is the resulting volume of the gas?

Text Solution

Verified by Experts

Given
`V_(1)=200mL`
`P_(1)=0.720mL`
`P_(2)=0.900`bar
`V_(2)=?`
`V_(1)P_(1)=P_(2)V_(2)`
`thereforeV_(2)=(P_(1)V_(1))/(P_(2))=(0.720xx200)/(0.900)=160mL`
