. The molality of the solution is [Given that molecular mass of 
]
Text Solution
Verified by ExpertsThe correct answer is:
C
Density 
Conc. of solution 
Molar mass of sodium hydroxide 
Volume of solution 
Mass of Solution = d 
V =1.28 
1000 =1280 g
Mass of Solute = Number of Moles 
Molar Mass
=2 
40 = 80 g
Mass of solvent 
Number of moles of solute 
Molality
