A compound H 2 X with molar weight of 80g is dissolved in a solvent having density of 0.4 gml – 1 . Assuming no change in volume upon dissolution, the molality of a 3.2 molar solution is
Text Solution
Verified by ExpertsThe correct answer is:
8
(8)Here, V solution 
V solvent
Since, in 1 
solution, 3.2 moles of solute are present,
So, 1 
solution 
1 
solvent (d = 0.4g/ml) 
0.4 kg
So, molality (m) =
