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

here is ur answer....

mass of the total solution=100g
density of solution=1.2g/ml

volume of the total solution =100/1.2=83.33ml

1) normality=(80/83.33×63) 1000=15.238N

2) molality=
mass of solute/ mass of sollvent× molecular mass× 100

80/20×63×100=63.49

hope it will help you

Answer 2

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
