An aqueous solution containing 36.7 g of an unknown substance in 308 g water was found to have a freezing point of -2.87 .C
- An aqueous solution containing 36.7 g of an unknown substance in 308 g water was found to have a freezing point of -2.87 .C. Calculate the molar mass of the unknown substance (Kf for water is 1.86 .C/m)
- Using the relation, ΔT f =mK f
- Hence,
- 0.64=1.86×m
- ⇒m=0.344
- ⇒ continue....
