1 mole urea and 1 mole NaCl are added to water Kf = 1 86, Kb = 0 52(in K - Chemistry - Solutions

Question

1 mole urea and 1 mole NaCl are added to water Kf = 1
86, Kb = 0 52(in K kg/mole) , determine the ratio of
deltaTb v/s deltaTf for the solution (urea :
NaCl)

Anuradha Puri · Accepted Answer

Since moles of urea and NaCl are equal (1 mole each), the molality
will be same Therefore,

1 mole urea and 1 mole NaCl are added to water.Kf = 1.86, Kb = 0.52(in K kg/mole) , determine the ratio of deltaTb v/s deltaTf for the solution (urea : NaCl)

1 mole urea and 1 mole NaCl are added to water.K_f= 1.86, K_b= 0.52(in K kg/mole) , determine the ratio of deltaT_b v/s deltaT_f for the solution (urea : NaCl)
