Which statement about the composition of vapour over an ideal `1 : 1` molar mixture of benzene and toluene is correct ? Assume the temperature is constant at `25^(@)C` Vapour pressure data `(25^(@)C)`: `{:("Benzene",75 mm Hg,),("Toluene",22 mm Hg,):}`A. The vapour will contain higher precentage of benzeneB. The vapour will contain higher precentage of tolueneC. The vapour will contain equal amount of benzene and tolueneD. Not enough information is given to make a prediction |

Answer» Correct Answer - B `V = (W ("mass"))/(d) = (205.5)/(0.79) = 260.13 mL` `M = (w_(B) xx 1000)/(m_(B) xx V)` `= (5.5 xx 1000)/(36.5 xx 260.13) = 0.58 M` |
