Question

Vapour pressure of CCl4

at 25°C is 143 mm. If 0.5 gm non volatile solute is added in 100 cm3

of

CCl4

calculate vapour pressure of the solution (density of CCl4

= 1.58 gm/cm3

)

(A) 141.93 mm (B) 94. 39 mm (C) 199.34 mm (D) 143.99 mm​

Answer 1

Explanation:

the vapour pressure of ccl4at 25 celcius is 143 mm hg . of 0.5 gm of a non volatile solute (mol. weight=65) is dissolved in 100 g ccl4, the vapour pressure of the solution will be.
