Calculate the freezing point of a solution that contains 1.75 mol of nacl dissolved in 1.00 kg of water. be sure to enter the new freezing point, and not the freezing point depression.

In order to calculate the new freezing point, we must first find the depression. This is given by:

ΔT = Kf * b * i

where Kf is the cryscopic constant for the solvent, b is the molarity of the solution in moles per kilogram and i is the van't Hoff factor, which tells us how many ions will be released when a substance is dissolved. 

Kf = 1.853, b = 1.5, i = 2 (Na⁺ and Cl⁻)

ΔT = 5.5 °C

The new freezing point will be 0 + 5.5
5.5 °C
