MHT CET 2023 Chemistry question
Calculate Van't Hoff factor of if 0.1 m aqueos solution of freezes at -0.43 K and cryoscopic constant of water is 1.86 K mg mol
Answer: (A)
Solution
Depression in freezing point . Here K (the solution freezes 0.43 below the freezing point of water), and . So \frac{Δ T_f}{K_f m}\frac{0.43}${1.86 ×
