Calculate the mole fraction of Co, in one litre of soda water sealed under a pressure of `"3.5 bar at 298 K". K_(H)=1.67xx10^(3)" bar"`

Text Solution

Verified by Experts

`"W.K.T      "P=K_(H)x`
Given
`"Pressure = 3.5 bar          "P_(CO_(2))=K_(H)X_(CO_(2))`
`K_(H)=1.67xx10^(3)" bar         "X_(CO_(2))=(P_(CO_(2)))/(K_(H))`
`=(3.5)/(1.67xx10^(3))=2.095xx10^(-3)`
