Question

solution of caustic soda contains 20% NaoH by weight.Taking density of the solution as 1.196kg/l.Find the normality,molarity,and molality of the solution.

Answer 1

Answer:

Let x be the mass of solution. Mass of NaOH=100x×20 . Molar mass of NaOH=40g. ∴ Number of moles= (1 0020x)/40=200x. Now mass of solvent in the ...
