The mole fraction of helium in a saturated solution at 20^(@)C is 1.2x – InterviewSolution

1.	The mole fraction of helium in a saturated solution at 20^(@)C is 1.2xx10^(-6). Find the presssure of helium above the solution. Given Henry's constant at 20^(@)C=144.97" bar".
Answer» <P> Solution :`p_(He)=K_(H)xx x_(He)=(144.97xx10^(3)" bar")(1.2xx10^(-6))=0.174" bar."`
