Q. No.In an ideal solution \(\mathrm{1 ~mol}\) of liquid \(\mathrm{A}\) and \(\mathrm{3~ mole}\) of liquid \(\mathrm{B}\) are present, total vapour pressure of solution is \(\mathrm{500~ mm}\) of \(\mathrm{Hg.}\) Vapour pressure of pure \(\mathrm{A}\) is \(\mathrm{200~ mm}\) of \(\mathrm{Hg}\) and vapour pressure of pure \(\mathrm{B}\) is \(\mathrm{x ~mm}\) of \(\mathrm{Hg.}\) Find the value of \(\mathrm{x}\):
1. \(\mathrm{1800}\)
2. \(\mathrm{600}\)
3. \(\mathrm{900}\)
4. \(\mathrm{500}\)
1. \(\mathrm{1800}\)
2. \(\mathrm{600}\)
3. \(\mathrm{900}\)
4. \(\mathrm{500}\)
