...depression that was witnessed. Were your? 3. Determine the molality (m) of Solution #1 remembering the Kfp of water is -1.86 oC/m for water and, since antifreeze is covalent, the value of i is 1. Use the following equation: (25 points)
ΔTfp = Kfpmi
5.6oC =-1.86oCm*1
1*5.6oC=-1.86oC(m)*1 m
5.6oC=-1.86oCm
5.6oC/-1.86oC
M=-3.01
4. Determine the molality (m) of Solution #2 remembering the Kfp of water is -1.86 oC/m for water and, since antifreeze is covalent, the value of i is 1. Use the following equation: (25 points)
ΔTfp= Kfpmi
7.2oC =-1.86oCm*1
1*7.2oC =-1.86oCm*1
7.2oC =-1.86oCm
7.2oC /-1.86oC
M=-3.87
