1. Freezing Point Depression
Lab Calculations

2. General Info D = data C = calculations
PT = mass off the periodic table
Measured = number came from the lab

3. Data
Measured
D2 – D1
D5-D4
See your notes (in oC)
0-D8

4. Calculations See notes for set up. Use D6
Use the freezing point depression equation (see notes) i=1 m=?
Mass = mass solute
m X kg
mass = D3
C2XC1

5. Calculations
Use the PT to calculate the total mass of the solute. Units are grams
%error = theo – expt X100
theo
%error = C4-C3 X100 C4

6. Conclusions See calculations See notes See calculation
YOU CANNOT USE – human error, math error, or my lab partner sucks
