The partial pressure of ethane over a saturated solution containing `6.56 xx 10^(-2) g` of ethane is 1 bar. If the solution contains `5.00 xx 10^(-2) g` of ethane, then what shall be the partial pressure of the gas?

Explanation

Applying the relationship `m=K_(H)xxp`
`"In the first case, "6.56xx10^(-2)g=K_(H)xx"1 bar or "K_(H)=6.56xx10^(-2)"g bar"^(-1)`
`"In the second case, "5.00xx10^(-2)g=(6.56 xx10^(-2)" g bar"^(-1))xxp or p=(5.00xx10^(-2)g)/(6.56xx10^(-2)" g bar"^(-1))="0.762 bar."`
