1.	A mixture of toluene and benzene boils at `100^(@)C`. Assuming ideal behaviour, the mole fraction of toluene in the mixture is closest to [Vapour presure of pure toluene and pure benzene at `100^(@)C` are 0.742 and 1.800 bar respectively. 1 atm = 1.013 bar]A. 0.824B. 0.744C. 0.544D. 0.624
Answer» Correct Answer - B `1.013=0.742X_(t)+1.8 X_(b)` `1.013=0.742(1-X_(b))+1.8 X_(b)` `X_(b)=0.256` `:. X_(t)=1-X_(b)=0.744`
