Achemist makes a solution of 1.33 mol cacl2 and 800 kg water, and then discovers that the freezing point of the solution is significantly less than 0°c. how could the chemist change the solution to increase the freezing point?

The chemist could reduce the amount of CaCl2 dissolved in the water and thus reduce the freezing point. The reason is that water freezes at 0 degrees C so if the solution is less than 0 degrees C then to approach the 0 degrees C again, the CaCl2 needs to be reduced.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

Must be negative.substance increases
