Question

2.34 Benzene (C6H) and toluene (C6H3CH3) form an
ideal solution. At 313 K, the vapour pressures of
pure benzene and toluene are 160 mm Hg and 60
mm Hg respectively. Calculate the partial pressures
of benzene and toluene, and the total pressure of the
solution when
(i) equal masses of benzene and toluene are mixed
at 313 K
(ii) equal moles of benzene and toluene are mixed
at 313 K:
(iii) 1 mole of benzene and 4 moles of toluene are
mixed at 313 K.​

Answer 1

Answer:

Solution B contains equal masses of both A (total pressure P_{B} ). The vapour pressure of benzene and toluene are 160 and 60 mm Hg respectively at 313 K.
