What is vapour pressure of a solution containing 1.8 g glucose in 16. 2 ~g of water if vapour pressure of water is 32 ~mm Hg ?

Options

  1. A22. 2 ~mm Hg
  2. B26. 6 ~mm Hg
  3. C24. 6 ~mm Hg
  4. D31. 7 ~mm Hg

Correct answer

D. 31. 7 ~mm Hg

Step-by-step solution

aligned & P_A^ -P_A P_A^ =x_B n_B n_A & 32-P_A 32 = 1.8 180 18 16.2 & =0.0111 & P_A=32-0.3555 & =31.7 ~mm & aligned
