A 2 L vessel contains oxygen at a pressure of 380 mm Hg at `27^(@)C.140g` of `N_(2)` gas is introduced in the vessel. Will the pressure of gaseous mixture increase or decrease and do what extent?

Text Solution

Verified by Experts

`V=2L,p=380//760=0.5atm, T=273+27`
`=300K`
`pV=nRT`
`n=(pV)/(RT)`
`"Moles of oxygen present, n"=(0.5xx2)/(0.082xx300)`
`="0.041 mol"`
`"Moles of nitrogen added"=(1.40)/(28)="0.05 mol"`
Total moles of gases present `=0.041+0.05=0.091`
Now, pressure of gaseous mixture,
`p=(nRT)/(V)=(0.091xx0.082xx300)/(2)`
`=1.12`
`therefore" Pressure will increases to 1.12 atm."`
