Calculate and compare the freezing points of the following aqueous solutions: 0.0500 m CaCl, and 0.0500 m KCI. The freezing point depression constant, Ry, for water is 1.86 "C/mol.
A. The freezing points of both 0.050 m KC and 0.050 m CaCl, are the same namely, 0.186°C
B. The freezing point of 0.050 m KCl is - 0.279°C. The freezing point of 0.050 m Caci, is-0.186°C,
which is not as low as that of a potassium chloride solution of the same molality.
C. The freezing point of 0.050 m CoC, is 0.279°C. The freezing point of 0.050 m Klis-0.186"C.
which is not as low as that of a calcium chloride solution of the same molality.
D. The freezing points of both 0.050 m KCl and 0.050 m Cact, are the same namely,-0.279°C.

the correct answer would be d. hope this !

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
