Question
The temperature at which molarity of pure water is equal to its molality is :
Options
A.273 K
B.298 K
C.277 K
D.None
Solution
At 4oC i.e. 277 K density of water = 1 gm/ml
∴ 1 kg water ⇒ 1000 ml water = 1 lit.
∴ Molality & molarity remains same.
∴ 1 kg water ⇒ 1000 ml water = 1 lit.
∴ Molality & molarity remains same.
