Answer:
The molality of a 3.2 molar solution is 8 mol/ kg.
Explanation:
Solution:
In 3.2 molar solution,
We have amount of solute = 3.2 mol
Volume of solution = 1.0 L
Since there occurs no change in volume on dissolving solute,
Volume of solvent = 1L
Mass of solvent = (1.0L)(0.4 gmL-1)
= (10^3mL)(0.4 gmL-1)
=400 g =0.4kg
Molality of the solution = 3.2/0.4 =8molkg-1
