Biphenyl C12H10 is a nonvolatile nonionizing solute that is

Biphenyl, C12H10, is a nonvolatile, nonionizing solute that is soluble in benzene, C6H6. At 25

Solution

moles of byphenyl=14.1/154

=0.09155

so number of moles benzene=29.3/78

=0.3756

so pressure=100.84*0.3756/(0.3756+0.09155)

=81.0778 torr
