 A solution contains 32.5g of CaCl2 dissolved in 250g of water. Calculate the freezing point of this solution. Assume the equation Change in Tf = -1.86m is valid.

The following question is exactly the same but changing out CaCl2 NaCl.

In closing which is the better deicer due to the previous data?

-------------------

My next question is which has the lowest freezing point assuming densities equal 1.0g/ml. My problems lies with the units of measurement (circle one)

1.
A. 1.0g Urea/liter
B. 0.2% urea
C. 0.1 M urea

2.
A. 0.1 M urea
B. 0.1 M ethanol(nonelectrolyte)
C. 0.1 M KCL

3.
A. 10g NaCl/liter
B. 10g KCL/liter
C. 10g urea/liter

From your formula Change in Tf = -1.86m , what is m?

That should help you answer everything else.
