Question

Calculate the amount of ice that will separate out on cooling a solution containing 50g of ethylene glycol in 200g water -9.3⁰C (K_f for water =1.86K kf mol^-1).

Solution

$we know that ∆ T_{f} = \frac{K_{f} {xW}_{B} x 1000}{M_{B} {xW}_{A}} Given that W_{B} = 50 g ∆ T_{f} = 9.3 K_{f} = 1.86 K {kgmol}^{- 1} M_{B} = 62 W_{A} = ? 9.3 = \frac{1.86 x 50 x 1000}{62 x W_{A}} W_{A} = 161.29 g Hence aamount of ice separated from 200 g water = 200 - 161 - 29 = 38 - 71 g$
