What is te mass of solute having molar mass $60 g mol^{- 1}$ when dissolved in 98 gram solvent decreases its freezing point by $0.2 K$ ? (The numerical value of cryoscopic constant of solvent is 1.71)

Options:

Answer:

Solution:

$Δ Tf = K_{f} m$ $0.2 = 1.71 \times \frac{W _{B}}{60} \times \frac{1000}{98}$ $W_{B} = 0.687 g$
