Freezing Point Depression Lab Calculations

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

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

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

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

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