So guys, here you go. Ur first challanging question of Chemistry Q.BANK is coming up. Nudge me for solution.
Don't post the solution here. If you have done the question, its good. U R following the right path to IIT but don't post any solution here. And one more thing, please write the question in clearly understandable form using subscript,superscripts,appropriate symbols etc. You can submit the questions of all 3 sections of chemistry. No need to make a new post in the forum of organic or inorganic chem.
Its an easy question but requires good concept. Its a previous year JEE problem.
Q.1- The molar volume of liquid benzene(density=0.877g/ml) increases by a factor of 2750 as it vaporises at 200C and that of liquid toluene(density=0.867g/ml) increases by a factor of 7720 at 200C. A solution of benzene and toluene at 200C has a vapor pressure of 46 torr. Find the mole fraction of benzene in the vapour above the solution.
Ans = 0.73
