One litre of gas A at 2 atm pressure at ...

One litre of gas A at 2 atm pressure at `27^(@)C` and two litres of gas B at 3 atm pressue at `127^(@)C` are mixed in a 4 litre vessel. The temperature of the mixture is maintained at `327^(@)`C. What is the total pressure of the gaseous mixture?

A

3.93 atm

B

3.25 atm

C

4.25 atm

D

6.25 atm

`(P_(A)V_(A))/(T_(A))+(P_(B)V_(B))/(T_(B))=(P_("mix")V_("mix"))/(T_("mix"))`
`(2xx1)/300+(3xx2)/400=(P_("mix")xx4)/600implies(8+18)/1200=(4P_("mix"))/600`
`P_("mix")=(26xx600)/(4xx1200)=3.25` atm
