A vessel of 120 mL capacity is containing a certain mass of gas at `20^(@)C` and 750 mm pressure. The gas was transferred to a vessel, whose volume is 180 ml. Calculate the pressure of the gas at `20^(@)C`.

Text Solution

Verified by Experts

We are given that
`p_(1)=750 mm , V_(1) =120 mL, V_(2)= 180 mL`
We are to calculate the pressure of gas `(p_(2))` at `20^(@)C`.
According to Boyle.s law
`p_(1)V_(1) = p_(2) V_(2) ` at constant T
`750 xx 120=180 xx p_(2)`
`p_(2)=(750xx120)/(180)=500mm`
