Question: Find the expected freezing point of a water solution that contains 286g of aluminum nitrate (Al(NO3)3) in 8.5 kg of water. answer in celcius
Note the correct spelling of Celsius.
delta T = i*Kf*m
Determine the molality of 286 g Al(NO3)3 in 8.5 kg water. (molality = mols solute/kg solvent).Plug that in for molality in the freezing point equation I wrote first. You have Kf, the freezing point constant for water, you have molality, and i is the number of particles (in this case that is 4; i.e., 1 Al and 3 nitrate ions). Post your work if you get stuck.
