Question

concentrated nitric in a bottle is 80% nitric acid by mass .The density of this acid is 1.2g/ml.calculate the normality and milality.....

Answer 1

Because mass of total solution = 100g
Density of Sol. =1.2g/ml

Volume of total solution =100/1.2=83.33ml
1)normality=(80/83.33*63)
1000=15.238N

2)molality=mass of solution /mass of solvent*molecular mass*100
=80/20*63*100=63.49

Answer 2

Hey mate.....

here's ur answer.....

Mass of the solution...= 100 gram.
Density = 1.2g/ml

Molality =
Formula= Mass of solution/mass of solvent× Molecular mass×100

= 80/20*63*100 = 63.49.

Normality =
100/1.2=83.33ml
(80/83.33×63)
1000 = 15.238 N...

Hope it helps...
