Question

5.) What is the predicted value of i for NaCl?

6.) Calculate the molality of the solution (m)

Use the equation:

T_f (solution) – T_f (solvent) = –i K_f m

The freezing point of pure water is 0.00 °C

K_f for water is 1.86 °C/m

7.) Mass of solvent in grams
Add together the masses of the liquid water and ice added to the calorimeter. Convert the volume of liquid water to mass using 1.000 g/mL as the density of water (see procedure for volume used).

8.) Mass of solvent in kilograms
Use the metric definition 1 kg = 1000 g

9.) Moles of solute (mol)
