Consider the following experiment. Two tubes $($A and B$)$ are placed into a sealed container with air at P$=1$atm $($T$=20\backslash$deg C$).$ Tube A initially contains pure liquid benzene.Tube B initially contains pure water.At equilibrium, there is still liquid benzene re$-$maining in Tube A$,$ and some benzene has dissolved in Tube B$.$ Compute: The partial pressure of benzene in the air

The concentration of benzene dissolved in Tube B
