what mass of salt (nacl)(nacl) should you add to 1.76 ll of water in an ice cream maker to make a solution that freezes at -14.8 ∘c∘c ? assume complete dissociation of the naclnacl and density of 1.00 g/mlg/ml for water.

The mass of salt is 196.5 g NaCl.

The collinear characteristics of solutions that the freezing point of a solution formed by the addition of a solute is lower than the freezing point of the pure solvent.

Remember the electrolytes freezing point formula.

T f = i K f m, where m is the molality of the solution, K f is the solvent's molal freezing point constant, and I is the solute's Vaunt Hoff factor relating to the number of ions created in solution.

solute mass = (T f) (MW) (mass of solvent in kg)

(1180 mL) (1.00 g/mL) (1kg1000 g)

=1.18kg is the mass of water in kilograms (i K f).

When we calculate the mass of NaCl, we obtain:

NaCl mass = (T f) (MW)

i K f mass of NaCl =−(−10.6 C) (58.4 g/mol) (1.18 kg) (2(1.86 C/m)
=196.5 g NaCl
