If 10^(-4)dm^(3) of water is introduced into a 1.0dm^(3) flask at 300 K, how many moles of water are in the vapour phase when equilibrium is established? (Given : Vapour pressure of H_(2)O at 300 K is 3170 Pa, R=8.314JK^(-1)mol^(-1))

Answer»

`5.56xx10^(-3)` MOL
`1.53xx10^(-2)` mol
`4.46xx10^(-2)` mol
`1.27xx10^(-3)` mol
