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.

A high school diploma is important to one's future. It is important because it proves one was willing to work hard to attain a high school education, and without one, it may potentially be difficult to obtain a job. Without a job, it hard to make enough money for a more than adequate life, as most people dream of. Another way a high school diploma is important to one's future is it allows them to further his or her education. High school diplomas look good to colleges and raise one's chances of getting accepted. In order to get into college, one just needs a G.E.D. or a General Education Diploma. High school and high school diplomas are very important to one's future because they help shape the outcome and help set up the amount of success that person will have. High school diplomas are important to one's future.
