(NH4)2SO4 vs Ce(NO3)4. Ammonium sulfate gives 3 ions in solution whereas cerium nitrate will give 5 ions in solution. So Ce(NO3)4 will have lowest freezing point.

Urea, with a melting point of 133-135 0C.
a) 0.25 molar is the smallest amount and thefore the lowest concentration of NaCl.
you can turn the graphics all down to the lowest point which stops it from freezing.

-30C(-22F) is listed as the freezing point for mineral oil. Due to viscosity (how thick the fluid is, basically), however, it's lowest useful temperature is considered to be 10C (50F).
