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:

Answer:

Solution:

$\frac{P _{A}^{\circ} - P _{A}}{P _{A}^{\circ}} = x_{B} ≃ \frac{n _{B}}{n _{A}} \frac{32 - P _{A}}{32} = \frac{1.8}{180} \times \frac{18}{16.2} = 0.0111 P_{A} = 32 - 0.3555 = 31.7 mm$
