The apparatus shown consists of three bulbs connected by stop cocks What is the pressure inside the system when stop cocks are opened ? Assume that the lines connecting the bulbs have zero volume and that the temperature remains constant Assume ideal nature for gases

`{:(P=2.13 atm,P=0.861atm,P=1.15atm,,),(V=1.50 litre,V=1.0litre,V==2.0 litre,,):}` .

Explanation

`V_(T) = 1.5 + 1.0 +2.0 =4.5L`
`P'_(CO_(2)) = (2.13 xx 1.50)/(4.5) =0.71 atm ( :' P_(1) V_(1) = P_(2) V_(2))`
`P'_(H_2) = (0.861 xx 1)/(4.5) = 0.19 atm`
`P'_(H_2) = (1.15 xx 2)/(4.5) = 0.51 atm`
`P_(T) = P'_(CO_2) + P'_(H_2) + P'_(Ar)`
` :. = 0.71 + 0.19 + 0.51 = 1.41 atm` .
