Calculate the relative lowering of vapour pressure if vapour pressure of pure solvent and vapour pressure of solution at 25^ C are 32 and 30 mm Hg respectively.

Options

  1. A0.0721
  2. B0.0552
  3. C0.0625
  4. D0.9375

Correct answer

C. 0.0625

Step-by-step solution

Relative lowering of vapour pressure = P ^0- P P ^0 = 32-30 32 =0.0625 Hg
