Tblarutan = Tb murni + delta Tb
100,39 = 100 + delta Tb
delta Tb = 100,39 - 100
= 0,39
Delta Tb = m x Kb
(Biasanya Kb itu 0,52 jadi sy pake 0,52 aja ya)
0,39 = m x 0,52
m = 0,75
(kf juga biasanya 1,86 jadi disini pake 1,86 ya)
delta Tf = m x Kf
delta Tf = 0,75 x 1,86
= 1,395
Tf larutan = Tf murni - delta Tf
= 0 - 1,395
= -1,395
smoga membantu, maaf kl ada yg salah di tahapnyaa :)
