1. Calculate the molar quantity
(number of moles) of glycerol from the
freezing point depression.
ΔTfp = Kfp . msolute.i.
2. Calculate the molar mass of glycerol
3. What is the difference between analytical grade salt (NaCl) and store-bought salt?
Given:
- 2.5g glycerol with 25mL water
- freezing point of Glycerol= -0.152⁰C
- Kfp of water= -1.86⁰C
- i=1
