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

Explanation

According to Henry's law
The mass of the gas (m) dissolved in solution `prop` Partial pressure (p) (At constant temperature)
`(6.56xx10^(-2g))prop"bar"`
`(5.0xx10^(-2)g)propp`
or `P((5.0xx10^(-2)g))/((6.56xx10^(-2)g))xx(1 "bar")=0.726`
