Hg(ClO₃)₂ is a non-volatile solute.
Mole fraction of water, X(H₂O)
= 1 - 0.224
= 0.776
Vapor pressure of the solution, P(H₂O)
= X(H₂O) * P°(H₂O)
= 0.776 * 23.8 mmHg
= 18.5 mmHg
Mole fraction of water, X(H₂O)
= 1 - 0.224
= 0.776
Vapor pressure of the solution, P(H₂O)
= X(H₂O) * P°(H₂O)
= 0.776 * 23.8 mmHg
= 18.5 mmHg
