Hexachlorophene is used as a disinfectant in germicidal soaps. What mass of hexachlorophene (406.9 g/mol) must be added to 125 g of chloroform to give a solution with a boiling point of 62.60°C?

(For chloroform, K_b = 3.63°C/m; boiling point of pure chloroform = 61.20°C)

Expert Solution

K_b = 3.63°C/m

boiling point of pure chloroform = 61.20°C

deltaTb = Kb*m

62.6-61.2 = 3.63*m

1.4 = 3.63*m

m = 1.4/3.63

m = 0.385m

molality = W*1000/G.M.Wt*wheighr of solvent in g

0.385 = W*1000/406.9*125

W = 0.385*406.9*125/1000

W = 19.58g

mass of hexachlorophene is 19.58g >>>>>answer
