31 ~g of ethylene glycol ( C ₂ H ₆ O ₂ ) is dissolved in 600 ~g of water. The freezing point depression of the solution is (K_f . for water is .1.86 ~K ~kg ~mol ⁻¹ )

Step-by-step solution

Given, W_B( mass of ethylene glycol )=31 ~g W_A (mass of water )=600 ~g K_f( for water )=1.86 ~K ~kg ~mol ⁻¹ and M_B ( . for . C ₂ H ₆ O ₂ )=62 array ll & T_f=K_f W_B M_B 1000 W_A & T_f= 1.86 31 1000 62 600 & =1.55 ~K array
