Step-by-Step Verified Solution
_ T f = K f m ......(1)
_ T b = K b m ......(2)
_ _ T f _ T b = K f K b .....(3)
_ T b = T 2 � T 1 = 100.18 � 100 = 0.18
k f
for water = 1.86 K kg mol �1
k b for water = 0.512 K kg mol �1
_ T f 0.18 = 1.86 0.512
_ _ T f = 0.654
_ T b = T 2 � T 1
_ 0.654 = 0 � T 2
_ T 2 = _ 0.654 o C
