The partial pressure of ethane over a saturated solution containing 6.56xx10^(-2)g of ethane is 1 bar. If the solution contains 5.00xx10^(-2) g of ethane, then what shall be the partial pressure of the gas ? |

Answer» <P> Solution :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."` |
