100,26-100= 0,26 (tb)
Tb= Kb x m
0,26=0,51 x (36/Mr) x 1000/400
Mr=176,5
Sori kalo salah

Dik: m air= 400 gr
m zar = 36 gr
Tb = 100,26 °c
dit: mr????
Tb=Tb°+delta Tb
100,26=100+delta Tb
delta Tb= 0,26
delta Tb = kb • n•1000/p
0,26= 0,51 . n 1000/400
0,26*400/510 = n
n=0,2
n=m/mr
0,2=36/mr
mr= 180
maaf kalo salah~
