Vapour pressure of chloroform (CHCl3) and dichloromethane (CH2Cl2) at 298 K are 200 mm Hg and 415 mm Hg respectively. The vapour pressure of the solution prepared by mixing 25.5 g of CHCl3 and 40 g of CH2Cl2 at 298 K is 347.9 mm Hg.
The mole fractions of each component, that is, CHCl3 and CH2Cl2 in vapour phase are respectively:
1 0.82; 0.18
2. 0.16; 0.84
3. 0.18; 0.82
4. 0.84; 0.16
