Given below are two statements :
Given : Molar mass of C, H, O, Cl are 12, 1, 16 and 35.5 g mol⁻¹, respectively.
Statement I : In 30%(w/w) solution of methanol in CCl₄ (at T K), the mole fraction of CCl₄ is equal to 0.33.
Statement II : Mixture of methanol and CCl₄ shows positive deviation deviation from Raoult’s law.
In the light of the above statements, choose the correct answer from the option given below :
(i) Let wt of solution = 100 g
wt of methanol = 30 g wt of CCl₄ = 100 − 30 = 70 g
Mole fraction of
= 0.3267 ≈ 0.33
(ii) CCl₄ & methanol is mixture of positive deviation from Raoult’s law.
So, statement (I) & statement (II) are correct.
Match List-I with List-II.
