The boiling points for pure water and pure toluene are $100$C and $110\mathrm{.}6$C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. The temperature at which the above mixture will exert a pressure of one standard atm. is

Less than $100$C

$100$C

Between $100$ and $110$C
