Gula 0,1 mol dan 3 mol garam LX2 dengan derajat ionisasi 0,5 masing - masing dilarutkan dalam 1 liter air (massa jenis air=1 g/ml). Jika penurunan titik beku larut gula t 0c, maka penurunan titik beku larutan garam LX2 adalah ...
Accepted Answer
The freezing point depression of a solution is directly proportional to the molality of the solute. Since the molality of the sugar solution is 0.1 mol/kg and the freezing point depression is t°C, the freezing point depression of the salt LX2 solution is 3
0.5
t°C = 1.5t°C. Therefore, the freezing point depression of the salt LX2 solution is 1.5t°C.
