What is vapour pressure of a solution containing 1 ~mol of a non-volatile solute in 36 ~g of water? ( P ₁^0=400 ~mm Hg )

Options

  1. A334 ~mm Hg
  2. B267 ~mm Hg
  3. C240 ~mm Hg
  4. D284 ~mm Hg

Correct answer

B. 267 ~mm Hg

Step-by-step solution

aligned & P ^ - P _ S P ^ = X _ solute = N _ solute N _ solute + N _ water & N _ water = 36 18 =2 & 400- P _ s 400 = 1 1+2 & (400- P _ s ) 3=400 aligned
