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; \[R = 8.314 J K^{-1}mol^{-1}\] )
a) \[5.56× 10^{-3}mol\]
b) \[1.53× 10^{-2}mol\]
c) \[4.46× 10^{-2}mol\]
d) \[1.27× 10^{-3}mol\]
